Redox titration?

What is this?

As soon as Ying Jianliao finished speaking, the waiting room remembered whispering.

"Oxidation-reduction titration? I've never heard of it..." Lin Yan heard someone ask him his doubts.

"It's an oxidation-reduction reaction." Liu Yiyuan smiled again, "Maybe I made a mistake by accident."

"I've heard of this!" The man's voice was full of admiration, "It's still Yiyuan."

Liu Yiyuan smiled modestly: "It's just a little dabble."

"But... didn't you say titration? Isn't titration a titration between an acid and a base?" Some people also voiced their doubts.

While everyone was still erratic, Ying Jianliao had already started to act.

The boy's pretty fingertips easily lifted the tripod, and skillfully turned the asbestos net to a slight angle, then weighed some potassium permanganate, made a solution of the purple medicine, and put it on the shelf .

Skillful movements, flowing clouds and flowing water, those white jade-like hands seem to have some kind of magic, which makes people unable to move their eyes away.

Lin Yan looked at Ying Jianliao's operation, feeling at a loss—didn't it mean redox?

What is Ying Jianliao doing?Build a toy?

Even so, Lin Yan's gaze was still fixed on Ying Jianliao's hands, watching the operation——

When he was studying, his grades were not good, and he felt sleepy when he was in class. Looking at Ying Jianliao's operations, Lin Yan felt...he might lack a good teacher.

But... is the net wrong?

Lin Yan was puzzled.

"Why does he have to test and release that net?" He couldn't hold back the doubts in his heart, and asked his idol in a low voice.

"Maybe it's because my hands are shaking and I didn't place it crookedly. This asbestos net is used for heat insulation, and I actually forgot to use it." Liu Yiyuan's voice was a little annoyed.

"It's okay, it's okay, it's better than putting it on the wrong side..." Lin Yan looked at Liu Yiyuan's expression, and hurriedly comforted his idol.

While the two were talking, Ying Jianliao on the screen had already started the next move.

The movements of his hands were clean and neat, and he took out the alcohol lamp without haste, lit it, and heated it up in one go.

Ying Jianliao's movements were simple and natural, with a relaxed expression. After the solution was prepared and transferred to the Erlenmeyer flask, Ying Jianliao took out the alcohol lamp and "snapped" the jumping flame on the alcohol lamp without any psychological burden. Sub cover off.

"Ying Jianliao can actually play with fire!" An actor beside Lin Yan exclaimed in a low voice when he saw the jumping flames.

"Ying Jianliao has something..." Someone sighed, and secretly glanced at Liu Yiyuan.

Lin Yan's heart tightened, and he also looked at Liu Yiyuan—so that's the case, no wonder his idol cared so much about Ying Jianliao.

On the screen, Ying Jianliao was still experimenting.

His operation is leisurely and leisurely, but his hand movements are very fast, and he is even able to coordinate and arrange time with ease - when cooling potassium permanganate, he picks up the acid burette and skillfully Rinse it a few more times.

Then everyone saw that Ying Jianliao skillfully poured the purple-red potassium permanganate into the upper mouth, and the purple liquid remained along the body of the burette. Considered a good experimental environment, it abruptly showed the feeling of a laboratory.

Lin Yan was fascinated by watching it—he felt as if he was watching a movie, and felt that he was Ying Jianliao at this time, pointing the country to the rows of reagents.

He couldn't help feeling secretly in his heart - Ying Jianliao, who was doing the experiment, was too similar to the chemical experimenter played by Chu Jue in "Indicator".

Lin Yan's eyes were fixed on the purple solution, and he was a little worried about Ying Jianliao.

He was afraid that if Ying Jianliao was not careful, he would stain the white lab coat with purple spots - no matter how good the performance was, it would be flawed.

I don't know how long I watched it, Lin Yan's glasses were sore, but Ying Jianliao barely leaked a drop.

Lin Yan's eyes were filled with disbelief.

Then Ying Jianliao stood up the acid burette, fixed it on the burette butterfly stand, and read the number with his eyes level.

Lin Yan was fascinated - although he didn't know what Ying Jianliao was doing, he couldn't take his eyes off.

He couldn't help leaning forward, eager to know what Ying Jianliao was going to do next.

Lin Yan didn't dare to turn his head to look at Liu Yiyuan's expression - he was already interested in Jianliao's performance in his heart.

He felt that this was the real way to do an experiment.

It doesn't even look like a show.

Lin Yan's narrowed eyes were filled with interest.

And Ying Jianliao on the screen has already started the titration.

Ying Jianliao held the lower end of the acid burette with white jade-like hands, his fingertips were slightly white, which complemented the clear purple in the frosted glass, creating a unique beauty.

Then, with the slight movement of the fingertip, a bean-sized drop of purple dripped from the thin tube and sank vertically into the Erlenmeyer flask below.

Looking at this scene, Lin Yan even began to plan in his heart - if it were to be filmed, the director would definitely zoom in for this shot.

After feeling over, Lin Yan reacted belatedly—unknowingly, the idol filter in his heart slowly disappeared.

Although I feel sorry for his idol, but... Objectively speaking, he feels that Ying Jianliao is indeed more suitable for this role than Liu Yiyuan.

Drops of purple liquid fell one after another, falling into the conical flask, fainting with a faint purple color, and then disappearing quickly.

I don't know how long it has been dripping, but the liquid in the Erlenmeyer flask is still transparent and colorless.

Lin Yan sat up straight, staring at the bottle that hadn't changed color for a long time, feeling a little disappointed in his heart—this is...the experiment failed?

Lin Yan couldn't hold back, and looked at the director's expression on the screen.

Jiang Lin remained expressionless, but the director and assistant director next to Jiang Lin frowned slightly.

"Just now, I thought it was a little tricky, but what is Ying Jianliao doing now..." Everyone watched the Erlenmeyer flask not change color, and began to discuss in low voices.

"Is this going to fail?"

"Why doesn't it change color?"

"He didn't add an indicator." Everyone was discussing, and Liu Yiyuan joined the discussion as if inadvertently.

"No wonder it hasn't changed color..." Everyone suddenly realized after listening to Liu Yiyuan's explanation.

"Hahahaha, so if you don't have diamonds, don't take the porcelain job, otherwise it would be really embarrassing..." The surrounding actors started whispering again, mixed with small laughter.

"Perhaps showing off that I know how to transfer solution? If I knew I would have made a transfer solution, it would be better than performing without a physical object." Some people also looked at Ying Jianliao, regretting too much.

"Yes, yes, there is no need to ignite this one. I was so nervous at the time that I didn't expect..."

"Transfer the solution, can you not spill a drop?"

Lin Yan couldn't hold back, and asked a question in return—just after he said it, he realized something, looked at his idol sadly, and quickly shut his mouth.

——It's all because Ying Jianliao's operation was so handsome just now, and he actually spoke for Ying Jianliao in front of Liu Yiyuan.

Lin Yan looked at Liu Yiyuan, then stared intently at the Erlenmeyer bottle in Ying Jianliao's hand, wondering for a moment whether he wanted the bottle to change color or not.

"It's going to change color."

Lin Yan was still struggling, but Chu Jue's voice came through the director, and there was a slight smile in the deep voice.

Will it really change color?

Hearing Chu Jue's determined tone, Lin Yan subconsciously wanted to believe it.

——He looked at the Erlenmeyer flask in Ying Jianliao's hand more eagerly.

But Lin Yan looked at the Erlenmeyer flask that had not changed color for a long time, and thought of what Liu Yiyuan said just now... a trace of doubt rose in his heart.

Seeing Ying Jianliao's unhurried operation, Lin Yan felt a little nervous.

It's like... the feeling of waiting for the results on the spot of the exam.

In fact, Ying Jianliao had already diluted the concentration of oxalic acid, and the titration didn't take much time. When Chu Jue called out to remind him, it was really just about to reach the end of the titration.

Ying Jianliao on the screen kept silent. Looking at the conical flask, the first drop oscillated around, and the color faded slowly as it dripped into the conical flask... Ying Jianliao finally said something.

"The next step is to operate with half a drop." A voice like mint bubbles sounded faintly.

Lin Yan was completely attracted by the voice.

He looked up, eyes fixed on the screen.

Ying Jianliao's white jade-like hand nimbly controlled the knob of the acid burette, and released half a drop of lavender solution from the burette. A purple water drop the size of a soybean hung on the tip of the burette, as if at any time. to fall.

Ying Jianliao's face remained normal, and the other hand approached the conical flask leisurely, sliding his fingertips, tilting the conical flask slightly, and lightly touched the half drop of purple solution with the neck of the conical flask .

Time seems to be pulled in slow motion.

Lin Yan just watched the purple drop of water slowly slide down the wall of the Erlenmeyer flask.

Finally fell into the clear and transparent solution.

Then everyone looked at it like this, the transparent solution that never faded before, and the moment this half drop fell into it, it was all dyed a light pink.

The color is very light, crystal clear in solution, charming and dreamy.

"It's changed color!"

"Fuck! It really changed color!"

"God, how did Chu Jue predict that his color would change? I have goosebumps..."

"Ying Jianliao is amazing! This is definitely going to study chemistry... It's too hard, too hard..."

Lin Yan's eyes were fixed on the Erlenmeyer flask, and he witnessed the moment when the Erlenmeyer flask was stained purple - tears welled up in his eyes.

Lin Yan turned his head away, and wiped away the little tears that came out.

what to do……?He wants to change his idol.

How can a serious man be so handsome.

Could this be the... charm of knowledge that I have never discovered since I was a child?

Suddenly thinking of something, Lin Yan looked at his idol Liu Yiyuan with a guilty conscience——

Lin Yan suddenly noticed... Liu Yiyuan's face also changed color.

His face turned green.

Guiltyly, Lin Yan moved a few steps away from Liu Yiyuan.

Then he looked at Ying Jianliao on the screen with adoring eyes.

After finishing the experiment, Ying Jianliao raised his head, shook the Erlenmeyer flask, and took off his glasses with one hand.

Then he put the conical flask on the table and rubbed his wrist lazily—titration is simple, but boring and tired.

Ying Jianliao raised his head and blinked, shook the lavender conical flask, and said cheerfully in his voice, "Well, it's done."

Then, as if remembering something, he added: "Oh, after the titration end point, the color will not fade within half a minute."

He looked at the silent director team with a serious expression, and then he remembered that this was an audition.

Ying Jianliao showed an expression of enlightenment, and smiled at the director again, his exquisite face was full of brilliance, as if ending a report, and came a standard ending: "This is the end of my audition, thank you for watching, please Everyone criticizes and corrects.”

After bowing, when Ying Jianliao looked at the director again, he felt a strong gaze beside him, burning his ass as if it had its own heat——

He turned his head and met Chu Jue's complicated eyes.

Then he heard Chu Jue's deep voice, and he also gave you some imperceptible praise: "This time the potassium permanganate didn't splash on the clothes, that's good."

Ying Jianliao was startled, his expression was like a cat that stepped on its tail——

It's over, it's over, I was too serious about doing the experiment just now, I forgot to cover up!

As if reacting to something, Ying Jianliao's expression became even more terrified——

Every time he uses potassium permanganate solution, he will definitely turn his clothes purple. Only Beria, who used to do experiments with him, knows this.

Ying Jianliao's pupils shrank.

Is it...? !
