Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula B(OH) 3. It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid. [3] It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite.
In this structure, there are two four-coordinate boron centers and two three-coordinate boron centers. It is a proton conductor at temperatures above 21 °C. Conductivity is maximum along the b-axis. [16] Borax is also easily converted to boric acid and other borates, which have many applications. Its reaction with hydrochloric acid to form ...
There are some claims that borax, in very small amounts, can be used as a nutritional supplement due to its boron content, but the risks outweigh the potential benefits, and it's not recommended ...
