The arsenius sulphide sol has negative charge the maximum coagulating power for precipitating it is of:
Correct answer: D. 0.1(N) AlCl3
- A. 0.1(N) Zn(NO3)2
- B. 0.1(N) Na3PO4
- C. 0.1(N) ZnSO4
- D. 0.1(N) AlCl3
Explanation
More the valency of cation greater will be its coagulating power as per hardy schulze rule.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
