Question

Can someone explain the formation of insoluble and soluble salts?

Answer 1

Precipitates can form when two soluble salts react in solution to form one or more insoluble products - as discussed in the famous example below. The insoluble product separates from the liquid and is called a precipitate.Precipitates can also form when the temperature of a solution is lowered. The lower temperature reduces the solubility of a salt, resulting in its precipitation as a solid.

Answer 2

the salts which are not soluble in water are called insoluble salts and the salts which are soluble in water are called soluble salts
