Start your trial now! WebDec 14, 2016 · In weakly acidic conditions, the dihydrogen phosphate ion ( H X 2 P O X 4 X −) is most common. In strongly acidic conditions, trihydrogen phosphate ( H X 3 P O X 4) is the main form. So, F e C l X 2 must somehow be acidic in aqueous solution so as to protonate potassium phosphate K X 3 P O X 4 to K H X 2 P O X 4. Is this statement true?
