Question

Define hardy schulre rule

Answer 1

Coagulation is a process which involves coming together of colloidal particles so as to change into large sized particles which ultimately settle as a precipitate or float on the surface.

Coagulation is generally brought about by the addition of electrolytes. When an electrolyte is added to a colloidal solution, the particles of the sol take up the ions which are oppositely charged and thus get neutralized. The neutral particles then start accumulating to form particles of a larger size which settle down.

The quantity of the electrolyte which is required to coagulate a definite amount of a colloidal solution depends upon the valency of the ion having a charge opposite to that of the colloidal particles. This observation of Hardy and Schulze are known as Hardy Schulze law.

It can be defined as: Greater is the valency of the oppositely charged ion of the electrolyte being added, the faster is the coagulation.

hope it helps u

thanks please

Answer 2

Answer:

Explanation:

Greater the valence of flocculation ion added, the greater is it's power to cause precipitation this is known as Hardy Schulze Law.
