Step-by-Step Verified Solution
According to hardy Schulze rule
_ Flocculating power of cation increases with increases in charge on cation of electrolyte in case of negatively charge colloid, hence order is
Al 3+ > Ba 2+ > Na +
_ Flocculating power of anion increases with increases in charge on anion of electrolyte in case of positively charge colloids
Hence order is
NaCl < Na 2 SO 4 < Na 3 PO 4
