Flocculation power increases with increase in the opposite charge of electrolyte.

Sure, I can explain this concept. Flocculation is a process where colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from precipitation in that, prior to flocculation, colloids are merely suspended, under the form of a stable solution, in a liquid and are not truly dissolved in a solution.

The flocculation power or efficiency of an electrolyte is its ability to cause the particles in a colloid to aggregate and form larger particles. This is often desirable in water treatment processes, where the goal is to remove small particles from the water by causing them to clump together and settle out of the solution.

The flocculation power of an electrolyte is influenced by the charge of the electrolyte. If the charge of the electrolyte is opposite to the charge of the particles in the colloid, the electrolyte can neutralize the charge of the particles. This reduces the repulsive forces between the particles, allowing them to come closer together and form larger aggregates.

So, as the opposite charge of the electrolyte increases, the ability of the electrolyte to neutralize the charge of the particles also increases. This leads to an increase in the flocculation power of the electrolyte. In other words, an electrolyte with a higher opposite charge is more effective at causing the particles in a colloid to aggregate and form larger particles.
