boric acid

Boric acid, Also called boracic acid, H3BO3, is a soft, colorless, crystalline solid and a weak inorganic acid. It occurs naturally in some volcanic hot springs. It gives boric oxide (B2O3) when strongly heated; sodium borate typifies its salts. Boric acid is used as an external antiseptic, in the production of glass, as a welding flux, and as an insecticide for ants and cockroaches.
