Factors Affecting Solubility

Crystallization – When you add a solid solute into a given concentration of this liquid solvent, the particles (solid) get dissolved in the solution. This process is termed as dissolution. Crystallisation occurs when the particles of solute collide with the particles present in solution, and some of it separates from the solution.Worksheet: Solutions Introduction Namec. crush the particles of the solid. d. chill the water. 9.
