In aqueous solution, boric acid B(OH) 3 can act as a weak Brønsted acid, that is, a proton donor, with pK a ~ 9. However, it more often acts as a Lewis acid, accepting an electron pair from a hydroxide ion produced by the water autoprotolysis: [11] B(OH) 3 + 2 H 2 O ⇌ [B(OH) 4] − + H 3 O + (pK = 8.98) [12]
Molar mass: 78.840 g mol −1 ... Thus, when boric acid is dissolved in pure (neutral) water, most of it will exist as tetrahydroxyborate ions. [citation needed]
