The boiling points of 0.01 M aqueous solution of sucrose, NaCl and CaC

1.	The boiling points of 0.01 M aqueous solution of sucrose, NaCl and CaCl2 would be - (A) the same (B) highest for sucrose solution (C) highest for NaCl solution (D) highest for CaCl2 solution
Answer» Correct Option :- (D) highest for CaCl₂ solution Explanation :- Q Elevation of boiling point is proportional to the no. of foreign species. CaCl₂ → Ca2⁺ + 2Cl^– ; 3 NaCl → Na⁺ + Cl^– ; 2 Sucrose remains an dissociated mostly ; 1

The boiling points of 0.01 M aqueous solution of sucrose, NaCl and CaCl2 would be - (A) the same (B) highest for sucrose solution (C) highest for NaCl solution (D) highest for CaCl2 solution

Answer»

Correct Option :- (D) highest for CaCl₂ solution

Explanation :-

Q Elevation of boiling point is proportional to the no. of foreign species.

CaCl₂ → Ca2⁺ + 2Cl^– ; 3

NaCl → Na⁺ + Cl^– ; 2

Sucrose remains an dissociated mostly ; 1
