Among the following statementsa) If two salts have equal solubility then their solubility products are equal.b) BaSO4 is more soluble in water than in dil.H2SO4c) When KI is added to PbI2, the [Pb2+] decreasesd) In any solution containing AgCl, the value of [Ag+][Cl-] is constant at constant temperature.

a) Solubility product depends on the formula type of the salt [so false]b) In dil.H2SO4, ions will be present. As a result of common ion effect solubility of BaSO4 in dil H2SO4 will be suppressed. [so true]c) KI is a strong electrolyte and so will furnish a high concentration of I- ions. As a result of common ion effect, solubility of PbI2 will be suppressed. [so true]d) This is an equilibrium. An equilibrium is characterised by a definite tremperature. [so true]
