Question

There are four major methods of purification in the chemistry laboratory. Which of the given techniques is not one of the four most common methods for separation and purification? distillation recrystallization extraction chromatography sublimation

Answer 1

The technique that is not one of the four most common methods for separation and purification in the chemistry laboratory is sublimation.

Step-by-step explanation:

The technique that is not one of the four most common methods for separation and purification in the chemistry laboratory is sublimation.

The four most common methods are distillation, recrystallization, extraction, and chromatography. Distillation separates substances based on differences in volatility, recrystallization separates based on differences in solubility, extraction separates based on differences in partitioning between two immiscible phases, and chromatography separates based on solubility and adsorption characteristics.

Answer 2

Answer:

Sublimation

Step-by-step explanation:

Sublimation is when a substance goes from a solid to a gas, without going through a liquid phase. This is not a method for separation and purification.
