In an experiment, addition of `5.0mL` , of `0.006MBaCl_(2)` to `10.0mL` of arsenic sulphite sol just causes the complete coagulation in `34h` . The flocculating value of the effective ion is:

Text Solution

Verified by Experts

sol is negatively charged owing to preferential adsorption of ions. Cation would be effective ion in coagulation.
Flocculating value millimole of the effective ion per litre of sol `50=0.06^3/(5+10)`
