The monohydroxyfluoroboric ion is quantitatively decomposed by the calcium ion at the room temperature, and the liberated acid may be titrated. On the other hand, the tetrafluoroborate ion is practically stable in this condition, but is decomposed by boiling. The mixture of monohydroxyfluoroborate and tetrafluoroborate is first treated at the room temperature and then at boiling; thus they are determined respectively., Article, 信州大学教養部紀要. 第二部, 自然科学 4: 27-31(1970)}, pages = {27--31}, title = {オキノフルオロホウ酸塩とフルオロホウ酸塩の分別定量法}, volume = {4}, year = {1970} }
