Question

Increasing order of solubility in water of hydroxide salts

Answer 1

Answer:

Group II metal oxide basicity and hydroxide solubility in water increase as you go down the column. The oxides of calcium, strontium, and barium are basic and the hydroxides are strongly basic. The solubilities of the hydroxides in water follow the order: Be(OH)2 < Mg(OH)2 < Ca(OH)2 < Sr(OH)2 < Ba(OH)2.
