Where is better Silver? For many people this is a strange object, and here's the introduction to it:
Silver nitrate is a colorless crystal that is soluble in water. Pure nitric acid is stable in light, but its aqueous solution and solids are often stored in brown reagents because of the lack of purity. It is used for photographic emulsion, silver-plated, mirror, printing, medicine, dyeing hair, testing chloride ion, bromide ion and iodine ion, etc., also used in electronic industry.
