Which of the following has maximum coagulating power in the coagulation of positively charged sol?

Which of the following has maximum coagulating power in the coagulation of positively charged sol?
  1. $\mathrm{Cl}^{-}$
  2. $\mathrm{SO}_4^{2-}$
  3. $\mathrm{PO}_4^{3-}$
  4. $\left[\mathrm{Fe}(\mathrm{CN})_6\right]^4$

Solution

Higher the charge more is the coagulating power. Hence $\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{4-}$ has high coagulating power.
