The minimum concentration of an electrolyte in millimoles per litre which is required to cause the precipitation of a sol in two hours is called as:
Show Hint
The coagulating value of an electrolyte is an important concept in colloidal chemistry, as it helps determine the minimum amount of an electrolyte needed to destabilize a colloidal system and cause precipitation.
The coagulating value is the minimum concentration of an electrolyte (in millimoles per litre) required to cause the precipitation (or coagulation) of a sol in two hours. The lower the coagulating value, the more effective the electrolyte is in precipitating the sol. The coagulating value is inversely related to the flocculating power of the electrolyte.
