WebCertain elements have more than one valency. They exhibit variable valency. For example, copper, tin, iron and mercury exhibit variable valency. Copper combines with oxygen to form cuprous oxide (Cu 2 O) and cupric oxide (CuO). Valency of oxygen being two, combining capacity of copper in the first case is one and that in the second case is two. WebJun 7, 2024 · 2) Increasing covalency leads to lower solubility in the salts (due to larger E L. For example, AgF, AgCl, AgBr, and AgI exhibit progressively lower solubility because of increasing covalency. AgF > AgCl > AgBr > AgI 3) Increasing the charge on the anion lowers the solubility because the increase in E L is large relative to the increase in E H.
