The coagulation of colloidal particles of the sol can be caused by
Coagultion 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 milli-moles per litre of the electrolyte solution which is 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. Coagulation value of the electrolyte alpha 1/("coagulating power") The coagualtion value of different electrolytes are different. This behaviour can be easily understood by hardy-schulze rule which states. "The greater is the valency of the effective ion greater is its precipitating power." The coagulation of colloidal particles of the sol can be caused by :
What is coagulation ?
Coagulation of blood takes place by

As_2S_3 sol is negatively charged, capacity to precipitate it is highest in which ion ?
A colloidal solution is subjected to an electrical field. The particles move towards anode. The coagulation of same sol is studied using NaCl, BaCl_2 and AIC_3 solutions. Their coagulating power should be
The separation of colloidal particles (or purification of sol) from particles of molecular dimensions is known as
