The electrolyte having maximum flocculation value for \( A g l / A g^{+} \)sol. is
- A \( \mathrm{NaCl} \)
- B \( \mathrm{Na}_{2} \mathrm{~S} \)
- C \( \mathrm{Na}_{2} \mathrm{SO}_{4} \)
- D \( \mathrm{Na}_{3} \mathrm{PO}_{4} \)
Answer & Solution
Correct Answer
(A) \( \mathrm{NaCl} \)
Step-by-step Solution
Detailed explanation
Flocculation value is inversely proportional to flocculationpower. For the flocculation of positively charged sol \( \mathrm{PO}_{4}{ }^{3-} \) ions
have maximum flocculation power while \( \mathrm{Cl}^{-} \)have minimum flocculation power. Therefore, \( \mathrm{NaCl} \) will have maximum
flocculation value.
have maximum flocculation power while \( \mathrm{Cl}^{-} \)have minimum flocculation power. Therefore, \( \mathrm{NaCl} \) will have maximum
flocculation value.
