Sodium bisulfite, a white crystalline powder. Sulfur dioxide odor. With an unpleasant taste. Exposed lose some of the sulfur dioxide in the air, and oxidized to sulfate. It was dissolved in 3.5 parts of cold water, 2 parts of boiling water, about 70 parts of ethanol, acidic aqueous solution. Melting point decomposition.
Hydrogen peroxide 27.5%
Hydrogen peroxide Chemical formula of H 2 O 2, pure hydrogen peroxide is light blue viscous liquid, can be mixed with water in any proportion, it is a strong oxidant, commonly known as aqueous hydrogen peroxide, a colorless transparent liquid. Their solution suitable for medical wound disinfection and environmental disinfection and sterilization of food. In general, it breaks down into water and oxygen, but the decomposition rate is extremely slow, speed up the reaction rate of the catalyst solution is added - manganese dioxide or short-wave rays.
