Boric acid
Boric acid (also know as orthoboric acid, boraic acid, and hydrogen borate) is mildly acidic substance, which is hydrate of boric oxide. It is an odorless white solid, typically sold as a powder.[1] It is used as a mild antiseptic, a mild antiviral agent, and as a fungicide and pesticide. It is generally cytotoxic to most living cells.[2] Its naturally occurring form is sassolite.[3]
Uses
Boric acid has a number of medical, household, and commercial applications. These range from insecticides to treatments for cold sores. It is toxic if eaten, which is generally the mechanism by which it kills insects. It prevents fungus from reproducing, and can kill plants by causing them to dry out.[4]
History
Boric acid was discovered by Wilhelm Homberg in 1702. He synthesized it by combining mineral acids, water, and borax.[3]
