solubility of Group II element

發問:

Why the solubility of the hydroxides of Group II elements in decending order? Ba(OH)2 > Sr(OH)2 > Ca(OH)2 > Mg(OH)2

最佳解答:

The solubility of the hydroxides of Group II elements in descending order is : 1.Ba(OH)2 2.Sr(OH)2 3.Ca(OH)2 4.Mg(OH)2 Because the reactivity of Ba(OH)2 is greater than Mg(OH)2 . In addition , the stronger reactivtiy of the hydroxide , the higer solubility of the hydroxide . --
