Question

colloids are stable how ? explain​

Answer 1

Answer:

This is due to the fact that most colloids are thermodynamically unstable, and their dispersed phase particles tend to aggregate. ... At the same time, adding a lyophilic colloid to a lyophobic sol can slow down the coagulation process and make a kinetically stable colloidal system.

Answer 2

$\huge \: Answer =$

The stability of a colloidal system is defined by particles remaining suspended in solution at equilibrium. Stability is hindered by aggregation and sedimentation phenomena, which are driven by the colloid's tendency to reduce surface energy.

Colloidal Stabilization :

Stabilization serves to protect colloids from aggregation and/or phase separation. The two main mechanisms for colloid stabilization involve steric and electrostatic modifications. Electrostatic stabilization is based on the mutual repulsion of like electrical charges. By altering the surface chemistry to induce a charge on the surface of particles it is possible to enhance the stability of the colloidal dispersion.
