What is Hardy Schulze rule? Which of the following electrolyte will coagulate most easily to positively charged colloid & why? Na3PO4, NaCl, Na2SO4

Answer»

Coagulating value of a coagulating ion is directly proportional to the charge on the ion.

Na₃PO₄will coagulate a positively charged colloid most easily because it has most negative valence.
