Otaku Engineer in Great Tang Dynasty Chapter 2155: The truth is revealed! (middle)

Remember 【New】for a second,! "That's right! Huanshengsan, which can bring dead fish back to life, was indeed made by a poor monk based on the textbook of "Chemistry" in the academy!"

In the room, Jia'e nodded. Seeing that the teachers and students were still puzzled, he continued: "You may still not understand when you say Huanshengsan. After all, this is just a name given by the poor monk himself, but If you talk about another name for it, you will probably understand that this Huanshengsan is actually sodium peroxide!"

"Sodium peroxide?"

Everyone couldn't help exclaiming, because the name was too familiar to them, Zeng Ziran murmured: "According to the textbook, the reaction between sodium peroxide and water will generate a lot of oxygen, is it because There is a lot of oxygen in the water, so the dying black fish will suddenly become alive, making people mistakenly think that it has come back to life?"

The teachers and students of the academy who can come to participate in the construction of the telegraph relay station are all strong and solid in engineering. Once Zeng Ziran said this, everyone was stunned, and they all turned their attention to Jia'e.

"This little benefactor said it well!"

Jiae glanced at Zeng Ziran, nodded approvingly, and said:

"The black fish used by the poor monk to perform the technique of resurrecting dead fish in the evening has been taken out of the water for half an hour before that. You should all know that fish can only use their gills to separate the oxygen in the water when they are in the water. However, it cannot separate the oxygen from the air, so if it is left in the air for a long time, the fish will suffocate and die!

The black fish was stranded for half an hour and was already dying, and the poor monk later put the fish in the fish tank, but the water in it was stagnant water with little oxygen, so even if the black fish entered the water, it was still very It is difficult to take in oxygen, and in the eyes of outsiders, it is almost a dying fish!

Gu If you have studied chemistry, you should all know that 2na2o2+2h2o=4naoh+o2↑, so when the poor monk poured a small amount of Huanshengsan, that is, sodium peroxide, into the fish tank, the peroxide Sodium reacts with water, and a large amount of oxygen will be produced in the water in a short period of time. The black fish, which is already deficient in oxygen, suddenly gets so much oxygen, and will naturally become alive and kicking! This is also the technique of resurrecting a dead fish in the eyes of the common people~! "

After listening to Gae's detailed explanation, everyone couldn't help but be amazed. Li Tai frowned and asked, "Although sodium peroxide reacts with water, although it will generate oxygen, it will also generate sodium hydroxide in the water. This substance is strongly alkaline, won't the fish die if they stay in the strong alkaline solution for a long time?"

Most of the students nodded secretly, apparently agreeing with Li Tai's question.

Jiae smiled and said, "Your Highness is a good question! However, the amount of sodium peroxide put into the fish tank by the poor monk at that time was relatively small. Even if sodium hydroxide was formed in the water, its The concentration will not be very high. The water in the entire fish tank is only in a weak alkaline state at most. Such water quality will not cause much impact on the tenacious black fish. Don't forget some salt, Your Highness. There are also many fish growing in the alkaline lake, that is to say, for some fish, the alkaline liquid environment will not affect their survival;

Second, due to the urgency of time, the poor monk had not actually done experiments with black fish before, and he was somewhat unsure, so in the evening, not long after he showed the people the resurrection technique of dead fish, The poor monk asked people to remove the fish tank, because he was worried that the black fish would slowly die due to the alkaline solution environment! His Highness had heard the windows of the guest rooms of the inn, and should have noticed this detail!

However, it was later proved that the poor monk's worries were unnecessary, because until all the people in Jian'an Fang received the fragrance, the black fish in the fish tank was still as lively as before! "
