Question

Which of the following is crystallization?

(a) Solid-solid separation

(b) Solid-liquid separation

(c) solid-gas separation

(d) Liquid- gas separation

The question was posed to me in homework.

My question is from Principles of Crystallization in section Crystallization of Food Processing Unit Operations

Answer 1

The correct answer is (b) Solid-liquid separation

To explain I would say: Crystallization is solidification of atoms into a highly structured form called a crystal. It is the solid-liquid separation and purification technique where mass transfer occurs from the liquid solution to a pure solid crystalline phase.
