A) 272.8 K
B) 272.79 K
C) 272.81 K
D) 272.6 K
Correct Answer: B
Solution :
Acetic acid is a weak acid\[({{K}_{9}}=1.8\times {{10}^{-5}})\]and ionizes to a very small extent hence,\[\Delta {{t}_{f}}\]for \[C{{H}_{3}}COOH\]solution is very slightly greater than that of urea solution. Therefore, freezing point of\[C{{H}_{3}}COOH\]solution will be slightly less than urea solution.
