Which chloride increases five fold in solubility upon heating to 100 c? question 4 options: silver chloride mercury chloride sodium chloride lead chloride iron chloride?

Lead chloride rises five fold in solubility on heating at temperature of  .

Solubility is defined as the capability of solute to dissolve in the solvent. It can be  determine in terms of maximum quantity of particle or solute is dissolved in a solvent at equilibrium.

Five fold in solubility refers to the five times increase in solubility. Maximum five folds of solubility can be obtained from lead chloride .

At room temperature, lead chloride is not soluble in water but in hot water lead chloride is soluble in water i.e. at .

Thus, five folds in solubility can be obtained from lead chloride in comparison to other chlorides as they don't give five folds in solubility.
