Text Solution

Verified by Experts

The correct Answer is:
D
`2mL` of `1MNaCl` contains `NaCl=(2)/(1000)=2` m mol
Thus `500mL` of `As_(2)S_(3)` sol require `NaCl` for complete coagulation `=2m mol`
Hence 1 L, i.e., `1000mL` of the sol require `NaCl` for complete coagulation `=4m mol`
Therefore, flocculation value of `NaCl=4` .
