Question
Which of the following electrolyte will have maximum flocculation value for Fe (OH)3 sol ?
Options
A.NaCl
B.Na2S
C.(NH4)3 PO4
D.K2SO4
Solution
Flocculating value ∝ 
, where z = valency of coagulating ion.
Since, (OH)3 is a positively charged sol so it will be coagulated by nagative ions con sidering the valencies of various nagative ions i.e., Cl-, S2-, PO43- and SO42-, we find that the valency of Cl- is least so it will have maximum flocculation value i.e NaCl.
