Critical Flocculation Concentration Schultze-Hardy Rule

4 Critical Flocculation Concentration Schultze-Hardy Rule 

Suspensions of colloidal particles exhibit different properties that are dependent on various parameters. One of these properties is that the suspension of solid particles will exhibit varying degree of stability. It is thus interesting to determine how these systems are stabilized as regards the various forces interacting between the particles. 

Solids in (colloidal) suspension can separate out of solution in various stages and pathways. The two most common pathways are as follows  

Stable suspension-flocculation-coagulation-sedimentation-particle separation 

Stable suspension-partial sedimentation-flocculation-coagulation-particle separation
