What is the appearance of these solutions? All oxides are insoluble EXCEPT those of calcium, barium and Alkali metal (Group 1, or, Group IA) cations; these soluble ones actually react with the water to form hydroxides (they are said to hydrolyse, and the reaction with water is known as a hydrolysis reaction ). Why did it take so long to notice that the ozone layer had holes in it? The chlorides, bromides, and iodides of all metals except lead, silver, and mercury(I) are soluble in water. The balance between the attraction of oppositely charged ions to one another and the attraction of separate ions to water dictates the solubility of ionic compounds. Solubility product calculations with 1:1 salts such as AgBr are relatively easy to perform. The carbonates become less soluble down the group. Answer 4: The reason why water dissolves salts is because it is polar; the hydrogen atoms are on one side of the oxygen, and acquire a partial positive charge, while the oxygen acquires a partial negative charge. All common acetates and nitrates are soluble. alkali metals and their ions M⁺): the solubility of M₂SO₄ decreases on going down the group; the solubility of M₂CO₃ increases on going down the group; all the MHCO₃ salts are soluble in water (not sure about it though); all the MOH compounds are soluble in water. 2.
