20ml of 0.1M of an electrolyte could cause flocculation of 980ml of a sol. What is the flocculation value of the electrolyte?

Text Solution

Verified by Experts

The correct Answer is:
2
`m = (n xx 1000)/(v) , n = (0.1 xx 20)/(1000) = 0.002 ` moles = 2 millimoles .

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 :
