Which of the following electrolyte will have maximum flocculation value for \(\mathrm{Fe}(\mathrm{OH})_{3}\) sol??
- A \(\mathrm{NaCl}\)
- B \(\mathrm{Na}_{2} \mathrm{~S}\)
- C \(\left(\mathrm{NH}_{4}\right)_{3} \mathrm{PO}_{4}\)
- D \(\mathrm{K}_{2} \mathrm{SO}_{4}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{NaCl}\)
Step-by-step Solution
Detailed explanation
Flocculation value \(\propto \frac{1}{\text { Coagulating power }}\) \(\mathrm{Fe}(\mathrm{OH})\) is a positively charged sol. For coagulating \(\mathrm{Fe}(\mathrm{OH})_{3}\) negatively charged electrolyte is used and greater the value of -ve charge, coagulating power will be…
