Q. Camphor is used as solvent to determine molecular weight of non-volatile solute by Rast method because for camphor

NTA AbhyasNTA Abhyas 2020Solutions

Solution:

Due to higher $K_{f}$ of camphor (40 K molality $^{- 1}$ ) about 20 times more than $K_{f}\left(\right.1.86\left.\right)$ of water, the depression is 20 times more in case of camphor used as solvent than water.
