Does any one know why in an LDH with M-N-X chemical formula, the M2+ and N3+ ions dissolve differently in aging condition? L/S and pH effect?

during aging of my LDH material, Ca and Al ions dissolve with different proportions in aging process. At pH 8, L/S 20 Ca dissolves more than Al. However, at pH 12, L/S 20 Al dissolved more....
