0.534 g of solute is dissolved in 15 g of water then freezing point temperature changes from 0oC to −1.57oC. Molal depression constant of water, Kf = 1.85Kkgmol−1. Find out: 0.01 M solution of KCl and CaCl2 are prepared in water. The freezing point of KCl is found to be −2oC.
The freezing point of 1% aqueous solution of calcium nitrate will be : When 3.24g of mercuric nitrate H g(N O3)2 dissolved in 1kg of water, the freezing point of the solution is found to be −0.0558∘C. When 10.84g of mercuric chloride H gCl2 is dissolved in 1kg of water, the freezing point of the solution is −0.0744∘C. Kf = 1.86mol−1 Kkg.
The molal freezing point constant for water is 1.86 K/m. Therefore, the depression in freezing point of 0.1 M N a C l solution in water is expected to be: Medium
The freezing point of. 1. %. of lead nitrate solution in water will be: A.
What is freezing point of 0.5 m solution (Kf = 1.86) When 3.24 g of mercuric nitrate, Hg(NO 3) 2 is dissolved in 1000 g of water, the freezing point of the solution is found to be −0.0558 0C. But when 10.84 g of HgCl 2 is dissolved in 1000 g of water, the freezing point depression is 0.0744 0C. K f for water is 1.86 0Cmolal −1.

If the elevation in boiling point of a solution of non-volatile, non-electrolytic and non-associating solute in a solvent (K b = x K k g m o l − 1) is y K, then the depression in freezing point of solution of same concentration would be:
The freezing point of benzene decreases by 0. 4 5 ∘ C when 0.2 g of acetic acid is added to 2 0 g of benzene. If acetic acid associates to form a dimer in benzene, percentage association of acetic acid in benzene will be: ( K f for benzene = 5 . 1 2 0 C .
Copper sulphate in ammonia solution form a complex which will lead to decrease the number of particles in solution. So, van`t hoff factor will decrease. Depression in freezing point and elevation in boiling point are directly proportional to the van`t hoff factor.
