Which of the following electrolytes will have maximum coagulating value for \(\text{AgI/Ag}^{+}\) sol?
- A \(\text{Na}_2\text{S}\)
- B \(\text{Na}_3\text{PO}_4\)
- C \(\text{Na}_2\text{SO}_4\)
- D \(\text{NaCl}\)
Answer & Solution
Correct Answer
(D) \(\text{NaCl}\)
Step-by-step Solution
Detailed explanation
The \(\text{AgI/Ag}^{+}\) sol is positively charged. Coagulating value is inversely proportional to coagulating power. Maximum coagulating value implies minimum coagulating power. Minimum coagulating power for a positive sol is provided by the anion with the lowest charge.…
