Chapter 234 Potassium Nitrate

"What's the matter, Ning'er? Do you want to keep what you're looking for a secret from me?" Xueyi asked again.

"No, it's just, I don't know how to tell you!" I said again not wanting to cause Xueyi's misunderstanding.

"What exactly are you looking for?" Xue Yi seemed even more curious.

I sighed, knowing that if I didn't tell him, he would definitely not give up, so I said helplessly, "I'm going to find potassium nitrate!"

"Potassium nitrate? What is potassium nitrate?" Xueyi asked even more strangely after hearing this.

I secretly felt a headache. I knew it would be like this if I said it.But how do I explain to him what potassium nitrate is?How to explain it clearly to him?Do you want me to tell him about chemistry and molecules?

Seeing that I didn't speak, Xueyi shook me and said: "Ning'er, tell me what that potassium nitrate is, so I can ask someone to find it for you!"

"Potassium nitrate is commonly known as fire nitrate or soil nitrate. Nitrogen and plant ash can be used as raw materials for the preparation of potassium nitrate. After the organic matter in the soil is decomposed, it is produced by the action of nitrous acid bacteria and nitric acid bacteria. Nitric acid and potassium in the soil , Na, Mg and other ions combine to form nitrate. This is how the nitrate in nitrate comes. Nitrate generally exists in toilets, pigs, cowshed houses, old walls of courtyards, cliffs, caves and places that are not easily washed by rain The ground. The nitrate soil is wet, not easy to dry, and it turns slightly purple after being exposed to the sun. When a good nitrate soil is placed on the red charcoal, sparks will burst out." Xueyi asked me a little bit, so I simply followed the book. I have memorized all the above.It doesn't matter whether he understands or not.

After Xueyi listened to my words, she was really stunned.After a while, he said: "Ning'er, I don't understand what you are talking about!"

Just don't understand!I thought to myself.It would be amazing if you could understand it!
"But, I know that the things you are looking for can be found in toilets, pig and cow stables, the foot of the old courtyard walls, cliff edges, rock caves and ground that are not easily washed by rain, right?" Xueyi continued to ask. road.

I was speechless, but still nodded.

"However, where is this toilet?" Xue Yi suddenly frowned and asked again.

"The cottage!" I said, rolling my eyes.
