Hydrogen Sulfide Nitric Acid
Hydrogen sulfide and nitric acid
In the past, there were scholars who studied the theory of chemistry in the study. One day, I wanted to study the relationship between hydrogen sulfide and nitric acid, which is to purify the vessel and prepare two things.
Hydrogen sulfide, the smell is like rotten eggs, the color is absent and toxic. Nitric acid, the strong acid is also strong oxidizing, and the color is clear and strong.
The scholar used caution to guide hydrogen sulfide into the vessel containing nitric acid. In an instant, the color of the vessel changed, fog was generated, and the sound of "hissing" was smelled. In hydrogen sulfide, the sulfur is negative divalent, and the nature is reductive; in nitric acid, the nitrogen is positive pentavalent, and the strong oxidation is clear. When the two meet, they respond to redox.
In hydrogen sulfide, the sulfur increases in price, forming sulfur elemental or higher-valent sulfur compounds; in nitric acid, the nitrogen decreases in price, forming nitrogen oxides, or nitric oxide, which is red-brown in case of oxygen without color; or nitrogen dioxide, which is brown-red and pungent.
It should be completed, studied and observed, and recorded in detail. Sigh at the wonders of chemistry, the sympathetic nature of matter, and the endless changes. Therefore, the principle of chemistry can explore the secrets of material changes, and it is used by the world. It should also be done with caution to prevent danger.
