Answer :
NO, a size separation technique does not make sense for separation of one soluble and one insoluble salt.
To separate one soluble and insoluble salt, techniques of solvent extraction and evaporation, crystallization are used. Among these, evaporation is the best technique to separate the salts.
Size separation techniques sieving, sifting, and screening. These are used on the basis of differences in size, shape, and density between particles.
The technique of evaporation is used. The mixture of the two soluble and insoluble salts are added to water. The soluble salt is allowed to dissolve and the insoluble salt is filtered out. The soluble salt can be obtained by evaporating with water.
This method involves four stages :
- Titration
- Evaporation
- Crystallization
- Recrystallization
