Solution

The correct option is A 2
In an experiment, addition of 5.0 mL of 0.006 M BaCl2 to 10.0 mL of arsenic sulphite sol just causes the complete coagulation in 34 h.
The flocculating value of the effective ion is 2.
As2S3 sol is negatively charged owing to preferential adsorption of S2 ions.
Cation would be effective ion in coagulation.
Flocculating value = Millimoles of the effective ion per litre of sol =5×0.006×1035+10=2
