Borate ion

The boron cation, B 3 +, exists in aqueous solution as undissociated boric acid B (OH) 3 and as the borate ion B (OH)4−. Formation waters with pH values lower than 9 favor B (OH) 3 as the predominant species, because the pK values for following reaction [1]: [1] B(OH)4 - borate = (BOH)3(aq) boricacid + (OH) − Borates are boron-oxygen compounds, which form boron oxyanions.
