What is Arsenous Acid?
Arsenous acid is a chemical compound that looks like clear water. It is known as a weak acid, meaning it's not as strong or corrosive as some other acids. When it mixes with other chemicals called bases, it creates new substances known as arsenite salts.
Why is it Dangerous?
It is very poisonous and can be harmful. Because of this, it must be handled with extreme care by trained professionals.
How it Behaves
You cannot find arsenous acid as a solid crystal. This is because it quickly changes back into arsenic trioxide and water. It is similar to another acid called phosphorous acid. However, arsenous acid does not have the same strong ability to cause chemical reactions that remove oxygen or add hydrogen, which is called being a "reducing agent."
How is it Made?
Arsenous acid is made by dissolving arsenic trioxide or arsenic trichloride in water. Think of it like dissolving sugar in water, but with these specific arsenic compounds.
