JEE Main & Advanced Chemistry Solutions / विलयन Question Bank Depression of freezing point of the solvent

  • question_answer
    The freezing point of a 0.01M aqueous glucose solution at 1 atmosphere is \[-{{0.18}^{o}}C\]. To it, an addition of equal volume of 0.002 M glucose solution will; produce a solution with freezing point of nearly          [AMU 1999]

    A)                 \[-{{0.036}^{o}}C\]          

    B)                 \[-{{0.108}^{o}}C\]

    C)                 \[-{{0.216}^{o}}C\]          

    D)                 \[-{{0.422}^{o}}C\]

    Correct Answer: C

    Solution :

              \[\Delta {{T}_{f}}=\frac{{{K}_{f}}\times 1000\times w}{m\times W}=-{{0.216}^{o}}C\]
