Hydrogen Sulfide Gas Formula
Smell the sulfur gas, I want to explain its formula. Sulfur and hydrogen combine to form hydrogen sulfide. Its formula is $H_2S $, dihydro-sulfide. This gas smells like rotten eggs, toxic and dangerous. It can be tested in the room. Sulfuric acid and ferrous sulfide combine, put in a Kip generator, and get slightly hot. Its gas encounters a wet blue litmus test paper, and the paper turns red because of its acidity. It can also turn lead acetate test paper black and form lead sulfide. Knowing this formula and nature is very beneficial to the study of chemistry.
