Boric acid `B(OH)_(3)` is weak monobasic acid reacts with alkali to form borates. The most common borate of boric acid is borax represented as `Na_(2)(B_(4)O_5(OH)_4.8H_2O` which is made up of two tetrahedral and two triangular units. On dissolution in water, these tetrahedral and triangular units are seperated. Borax is useful primary standard for titra tion against acids
