• A. (a) - (q), (b) - (s), (c) - (p), (d) - (r)
• B. (a) - (p), (b) - (s), (c) - (q), (d) - (r)
• C. (a) - (r), (b) - (s), (c) - (p), (d) - (q)
• D. (a) - (r), (b) - (s), (c) - (q), (d) - (p)

Answer 1

Answer: (B)

(a) - (p), (b) - (s), (c) - (q), (d) - (r)

Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.
Salt and ammonium chloride can be separated using this.

Crystallization is also a chemical solid-liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.
Pure copper sulfate from an impure sample.

Distillation is the process of separating the component substances from a liquid mixture by selective evaporation and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture.

A separating funnel is a glass funnel with a tap at the bottom. A separating funnel is a separation technique that is used for two liquids that do not dissolve in each other.
