Question
Select correct statements :
Options
A.The fundamental cause of all colligative properties is the higher entropy of the solution relative to that of the pure solvent
B.The freezing point of hydrofluoride solution is larger than that of equimolal hydrogen chloride solution
C.1M glucose solution and 0.5 M NaCl solution are isotonic at a given temperature
D.All are correct statements
Solution
In HF hydrogen bonding is present so there is association of molecules due to this van′t hoff factor is less, so depression in f.p decreases therefore f.p. value is larger than HCl. Similarly value of i = 2 for NaCl and i = 1 for Glucose.
