Question

Arrange the following process in the correct order of obtaining pure salt crystals from impure salt.
A. Crystallization of Salt
B. Preparing saturated solution
C. Heating saturated solution

Answer 1

• To obtain pure crystals of salt, the impure salt is first dissolved in water until the solution becomes saturated with a small amount of undissolved salt left in it.
• This saturated solution is then heated to allow excess salt to dissolve in water.
• At last the pure salt crystals are collected over the filter paper as a residue and then dried.
• So, the correct order is B-C-A
