Question

_______ (Rast/Solvey) method involves the determination of the melting point of camphor and its solution.

Answer 1

Rast method involves the determination of the melting point of camphor and its solution. Rast method is used to identify the molecular mass of an unknown solute. In this method, we have to identify the depression of 'freezing point' of the solution after the addition of solute to it which in turn helps is used to identify the molecular mass of an unknown solute.
