Webthe BF3-H2O was prepared by mixing BF3-CH3OH with large amount of water, in which the stoichiometric concen- tration of BF3 is less than 0.1 mol/L. Two ionic equilibrium models were proposed to simulate the hydrolysis equi- librium of BF3 and tested by special acid-base titration technique. The most accurate ion equilibrium constants were WebHBF3OH + HF ~- HBF4 + H20. (2) Part of the tetrafluoboric acid is dissociated in solution, yielding F- by hydrolysis of BF2, which reacts with lanthanum: BF2 +3H20~BO3H3+4F-+3H + (3) 6 F- + 6 H + + La203 ~ 2 F3La$ + 3 H20.
