Question
Ca3(PO4)2 is insoluble in water. On adding a few drops of HCI to solid Ca3(PO4)2 in contact with water, the solid dissolves. The reason is:
Options
A.The solvent becomes more polar on adding HCI
B.Ca3(PO4)2 combines with HCI to form soluble CaCI2 and H3PO4
C.Ca(H2PO4)2 is formed, which dissolves
D.H3PO4, a weak acid is formed and the solubility product of Ca3(PO4)2 decrease
Solution
Ca3(PO4)2 + 6HCI → CaCI2 + 2H3PO4
soluble
soluble
