Hardy Schulze law: Ions carrying opposite charge are effective in coagulation of solution and the coagulating power is directly proportional to the valency of the ion. For negative colloid (As2S3sol) the order of precipitation will be as follows Fe3+ > Ba2+ > Na+ ions.  For positive colloid the order of precipitation will be as follows (Fe(OH)3) PO43-> SO42- > Cl-.
