For More Understanding

Explanation

Camphor is a sublimable compound, whereas calcium sulphate is a non-sublimable impurity. The technique of sublimation is used to separate sublimable compounds from non-sublimable impurities by heating the mixture, causing the sublimable component to change directly from solid to vapour state without passing through the liquid state.

Solution Steps

  1. Step 1: Identify the nature of the components in the mixture. Camphor is a sublimable compound, while calcium sulphate is non-sublimable.

  2. Step 2: Apply the technique of sublimation, which separates sublimable compounds from non-sublimable impurities.
