high school chemistry, the teacher would have ammonia the things mentioned the toilet, so why the toilet with ammonia, where is the toilet ammonia source?
The ammonia in the toilet is actually produced by the decomposition reaction of urea in the urine. The ammonia odor is just a kind of unpleasant pungent odor, and the odor is not very obvious.
If you live in the countryside, you will find that ammonium bicarbonate (NH4HCO3), the old nitrogen fertilizer, is very volatile, which mainly attracts attention is the smell of ammonia, but not the same as the disgusting smell in the toilet.
In fact, most of the odor in the toilet mainly comes from feces. The reason is that feces produce many complex organic and inorganic chemicals in the formation process of the gut, such as skatole, indole, hydrogen sulfide, sulfhydryl, volatile fatty acids, nitroso amines, ammonia, especially the former two.
