This will be done by combining different amounts of the salt in similar amounts of water and heating the solutions until all of the solute completely dissolves. In addition, the change in solubility for a given salt, say between 20° and 30°C, may not be the same as the change in its solubility between 50° and 60°C. Most common chloride salts are soluble in water except silver chloride (AgCl), lead (II) chloride (PbCl 2). 0000000736 00000 n
