Lead Nitrate Sodium Sulfide
The experience of lead nitrate vulcanization
In the past, there were scholars who were proficient in the art of checking things. One day, I wanted to test the combination of lead nitrate and sodium sulfide.
Then I took a little lead nitrate and placed it in a purifier. Lead nitrate is white and pure in color, like fine sand, and has a peaceful nature. Take an appropriate amount of sodium sulfide. This is a yellow thing with a slight odor and a lively nature.
The scholar, in a cautious state, slowly poured sodium sulfide over lead nitrate. And then, a strange phenomenon arose. The two touched and changed. At first there was light smoke, then the color changed, and gradually it became dark. In Russia, the reaction intensifies, as if there is a desire for things to come out, and there is a pungent smell.
From the perspective of scholars, I think this is the reason for the competition of chemical properties. The quality of lead and nitrate, when it encounters sodium sulfide, its atoms combine and form a new thing. This new thing is dark and completely different from the previous two.
The wonderful thing about the study of things is to explore the change of physical properties. The test of lead and nitrate and sodium sulfide shows that the material is sympathetic, and the change is gratuitous. It is the mystery of nature. From this test, scholars have improved the principle of the system of physical properties, and have further advanced in the way of checking things.
