A solution is prepared by dissolveing 26.3g of CdSO_(4) in 1000g water. The depression in freezing point of solution was found to be 0.284K. Calculate the Van't Hoff factor. The cryoscopic constant of water is 1.86K kg solvent "mol"^(-1)-"solute" .

Depression of freezing point of which of the following solutions does represent the cryoscopic constant of water ?

Assertion (A): Larger the value of cryoscopic constant of the solvent, lesser will be the freezing point of the solution. Reason (R ): Depression in the freezing point depends on the nature of the solvent.
