Q25 / 160 · AP EAMCET 2024 (19 May Shift 2) · Chemistry

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

  • A
    $\mathrm{Cl}^{-}$
  • B
    $\mathrm{SO}_4^{2-}$
  • C
    $\mathrm{PO}_4^{3-}$
  • Correct answer
    D
    $\left[\mathrm{Fe}(\mathrm{CN})_6\right]^4$

Solution

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

Hence, the correct answer is option: 'D'.
