The electrolyte having maximum flocculation value for ( A g l / A g⁺ )sol. is

Options

  1. A( NaCl )
  2. B( Na ₂ ~S )
  3. C( Na ₂ SO ₄ )
  4. D( Na ₃ PO ₄ )

Correct answer

A. ( NaCl )

Step-by-step solution

Flocculation value is inversely proportional to flocculationpower. For the flocculation of positively charged sol ( PO ₄ ³⁻ ) ions have maximum flocculation power while ( Cl ⁻ )have minimum flocculation power. Therefore, ( NaCl ) will have maximum flocculation value.
