Which of the following has maximum coagulating power in the coagulation of positively charged sol?
- A \(\mathrm{Cl}^{-}\)
- B \(\mathrm{SO}_4^{2-}\)
- C \(\mathrm{PO}_4^{3-}\)
- D \(\left[\mathrm{Fe}(\mathrm{CN})_6\right]^4\)
Answer & Solution
Correct Answer
(D) \(\left[\mathrm{Fe}(\mathrm{CN})_6\right]^4\)
Step-by-step Solution
Detailed explanation
Higher the charge more is the coagulating power. Hence \(\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{4-}\) has high coagulating power.
