Ermin took the NaOH that was handed to her, thanked her, and took the burette from the butterfly clip, and Husky handed the funnel to Ermin.

"Is this also to prevent inaccurate results?" Ermine asked.

Husky shook his head, "This is to prevent the solution from being poured out, and since this is a strong base, be careful when pouring it out."

"When the huskies used sulfuric acid last semester, because the rubber hose was broken, a drop of sulfuric acid fell on their hands." Looking at Ermin carefully holding the bottle and slowly pouring NaOH into the burette, she said, " Although she wiped it off immediately, there was still a bump on her hand, which took almost two weeks to disappear."

When Ermin heard this, her hands couldn't help shaking.Husky grasped the upper part of the burette, "Phase, don't be scary at this time, otherwise accidents are really easy."

Looking at Husky, he blinked.

When Ermin had finished adding the solution, she put the burette back on the butterfly clip and, like a husky, put in a little solution and took the reading.Immediately Ermin put the Erlenmeyer flask under the burette, she opened the valve, and slowly shook the Erlenmeyer flask.Husky lay on the console and looked at Ermin, and she slowly closed her eyes.

"Is she all right?" Huskies vaguely heard Ermin asking the face softly.

"It's okay," Xiang replied in a low voice, "She just didn't sleep at noon, so she's a little sleepy now."

"Nap? Oh, what a baby."

What happened to the little baby?Huskies really want to refute, who said adults can't take a nap?But Huskies don't want to open their mouths, so they just close their eyes and take a rest.In the first two times, I used about 23,22 to [-] ml each time, except for the final stage, when I used it, it was almost...

Ermin and Xiang glanced at the husky, who was breathing steadily and was considered to be asleep, and chuckled lightly.Ermin immediately looked back at her Erlenmeyer flask.One drop after another of a colorless solution slowly fell into another colorless solution without any change.Just suddenly, that drop, the moment it touched the surface of the Erlenmeyer flask, the colorless solution turned pink and disappeared in a flash.

Ermin immediately closed the gate, followed Husky's example, opened it carefully again, and closed it again immediately, but her control was far less secure than that of Husky.

"How are you doing?" Rodwick asked softly, stepping over to their side for the first time since class.

"It's almost ready," Ermin said, trying to add just one drop of solution to the Erlenmeyer flask.

Rodwick nodded, and she picked up the other two finished Erlenmeyer flasks, looked at the almost invisible pink solution inside, "Hands are steady. Keep going."

The husky was finally woken up by the photographer. As soon as she opened her eyes, she first looked at the Erlenmeyer flask under the burette, but there was nothing there.

"Where's my Erlenmeyer flask?" Husky looked around immediately, and then she saw that beside the two Erlenmeyer flasks, there was another one, and the liquid in it fully proved that it was pink.

"Who did this?" Husky frowned, "The result..."

"The result is very good, isn't it?" Xiang interjected beside the pool, and she glanced at Husky to signal her not to talk nonsense.

"It's too popular..." Husky looked at the bottle tangled up. The data might be inaccurate and unusable.

Xiang immediately glared at Husky, and she glanced at Ermin who was concentrating on writing something on the experiment report.Husky pursed her mouth and swallowed what she wanted to say. She silently walked to the side of the sink, took the burette from the prime minister's hand, and started cleaning.

"Am I going to do it all over again?" Ermine asked, looking sideways.

"If you..." just as Husky said that, Xiang coughed, and Husky pursed his lips, "Generally speaking, when we deal with such experimental data, we just try to..."

Xiang immediately gave Husky an elbow.

Husky tightened his jaw, "This data is too different, we can't use it." Husky gritted his teeth, and whispered in Chinese, "This will affect our calculations."

"That's your goddess, Husky."

"But the experimental data can't be sloppy. When the time comes to calculate, the experimental error will be very large."

"We are not doing research for you now, the purpose is just for us to master this titration."

"Acid-base neutralization titration." Husky grumbled from his throat.

"Okay, okay. I'll help you find a reason, and you just say, even if we have to do it again, we don't have time."

"Others haven't done it yet, and it will take up to twenty minutes to do it again."

"That means there's not enough solution left to do it all over again."

"That's enough to do three times."

"You want to go back to sleep."

"I just woke up."

"That's your crush!"

"...But, but...then... then you find an excuse to go with her, and I will do it again myself."

"Do I need to do it all over again?" Ermin asked again.

Husky didn't answer, she turned her head to look at Xiang, who stared and warned her not to do it.But the Huskies glared back, not to be outdone.Finally, Xiang shook his head and walked towards the console.

"Generally speaking, for such data, although it may be only one or two milliliters more, because the pink color is relatively deep, this data is considered unreliable. And because we usually need three data to support One experiment, so, generally speaking, we're going to do another set."

"But what if we don't use this set of data?" Xiang asked, she glanced at the data written by Huskies, "and there is actually no big difference."

"If you want to do it again, I have no problem," Ermin said.

Husky turned off the faucet, she closed her eyes, pursed her lips, and made up her mind, "Okay, let's do it again. But," under the gesture of the prime minister's eyes, Husky quickly added, "It's the first time. That's actually pretty good. Ermin, would you mind passing me one of the three Erlenmeyer flasks? We're going to clear one out."

Rinse the burette and Erlenmeyer flask again, step by step, slowly and methodically.After Ermin finished the second time and got a data that satisfied Huskies, Huskies nodded in satisfaction, almost jumping to wash the utensils.

Although four groups were repeated, the huskies were not the last to walk out of the laboratory. Looking at the huskies in a good mood, they shook their heads.

"Then we'll see you tonight." Huskie said, nodding her head energetically, and then she waved to Ermin, and wanted to go to dinner.

"Are you with us too?" Xiang asked Ermin, Husky raised his head and looked at Ermin expectantly.

"Okay." Ermin nodded, "It happens that we can write the experiment report together after eating." Then she laughed, "And our data this time is very good."

"That's for sure." Husky nodded emphatically, "Bad data cannot be used."

Ermin laughed, and she pulled her hair back behind her ears. "I think you're right. There was a moment just now when I did feel the excitement and anticipation of waiting for the solution to change color. And finally When the color changes, that kind of sudden satisfaction."

"Yes, yes." Husky nodded excitedly, she simply turned around and walked backwards towards Xiang and Ermin, "Look, Xiang, let me tell you. When you successfully complete an experiment , and keep the experimental error to a minimum, this brings you a sense of satisfaction and success that nothing else can give you. It's like..."

Husky pursed her lips, and waved her hands in the air, as if trying to find a word that best described her current feeling.

"Very good, very good." They clapped their hands in unison, "Congratulations, you have found an ally."

"Alliance?" Husky tilted his head and thought about it. Alliance, um, seems to be a good possibility.

Huskies, Xiang and Ermin walked into the school cafeteria together. A small number of people stopped their movements when they saw Ermin, but soon they returned to normal.

A Husky that has slept for a while is like a sports car that has been refueled and revived.

"Honestly," Husky said excitedly when the three of them sat down at an empty table, "Ermin, if you want to learn more about science, I know there's an Good-looking American drama, I decided to study a department related to science, half of it was because of it. It talks about how to use..."

"Husky," Xiang called out, "I'm about to eat, can you stop talking about such a bloody thing."

Husky puffed his mouth and began to eat well.

"So," Ermin looked at them, "except for that American TV series that sounded scary, but was a bit scientific." When Ermin said this, she stopped, and she seemed to think for a while, what kind of American TV series? To be able to meet these two conditions, and, if there is such an American drama, how terrifying it would be. "Do you usually watch anything else?"

"I watch a lot of American dramas." Husky nodded excitedly, "For example..."

"A bunch of detective dramas." Xiang hurriedly said, preventing Husky from getting too excited and saying something that was not suitable for discussion at the dinner table.

"In addition to detective dramas, I also watch other things." Husky argued, "For example, there is a TV series in the UK called The Flying Thieves. There is a woman in it, and her British accent is super nice."

"Really?" Ermine asked in a British accent.

Huskies stood there immediately, his mind blank.

"She likes English accent very much," Xiang explained.

"Because I think they are very emotional." Husky came back to his senses, blushing a little, and she hoped that Ermin didn't misunderstand what she meant, or see through her little thoughts.Husky lowered his head and cut the ribs on the plate. "When my mother was young, she had a teacher who called me English accent, but..." Husky shrugged, and she laughed, "I never learned it."

"And what do you think of my accent?" Ermine asked again in British accent.

Husky's brain was short-circuited for a few seconds, then she blushed and lowered her head, "No, very, very good."

"So, Prime Minister, I never knew what your major was?" Ermine asked.

"Philosophy," Xiang said, "I want to study law in the future."

"That's great." Ermin nodded. "Do you want to stay in Columbia to study law, or go to another school? Do you know LSE? I know a guy who graduated from LSE born."

"I hope I can be admitted to Columbia." Xiang said, "I've heard of London Political Science and Economics, which is a very good school. In a few days, our school will have an introduction meeting for exchange students with political science and economics. I want to go to Listen, but they should have many conditions, and I may not be able to succeed."

"Good luck."

"Thank you."
