The coagulation of sol particles may be brought in by :

The coagulation of colloidal particles of the sol can be caused by

The coagulation of colloidal particles of the sol can be caused by

The coagulation of colloidal particles of the sol can be caused by

The coagulation of the lyophobic sols can be carried out by

coagulation is the process by which the dispersed phase of a colloid is made to aggregate and thereby separate from the continuous phase. The minimum concentration of an electrolyte in mili-moles per litre of the electrolyte solution which required to cause the coagulation of colloidal sol is called coagulation value . therefore higher is the coagulating power of effective ion, smaller will be the coagulation value of the electrolyte. the coagulation of colloidal particles to the sol can be caused by : heating, adding electrolyte, adding oppositely charged sol, all of these.

How coagulation of lyophilic sol is carried out?

Under the influence of an electric field, the particles in a sol migrate towards cathode. The coagulation of the same sol is studied using NaCl, N_2a_4S and N_3a_4P solutions. Their coagulating values will be in the order :
