The FeB(OH) 4 2+ formation constant result obtained in the present work isBβ 1 * = [FeB(OH) 4 2+ ][H+][Fe3+]-1[B(OH)3]-1 = (5.4±0.3) x 10-3 at 25.0°C and 0.7 molal ionic strength. Our result indicates that solution concentrations of FeOH2+ and FeB(OH) 4 2+ are approximately equal in aqueous solution for boric acid concentrations on the order of 0.3 molal. Fe(B(OH)4) 2 + is a minor species in solution compared to FeB(OH)4 2+ for conditions such that [B(OH)3][H+]-1≤ 350, and ferric borate complexation is insignificant in solutions such as seawater where [B(OH)3] ≤ 4× 10-4 molal.
