Question:medium

The pH of sodium formate solution in terms of Kₐ and the concentration of the electrolyte C is:

Show Hint

To avoid confusion with formulas: - Salt of Weak Acid + Strong Base: pH = 7 + (1)/(2) pKₐ + (1)/(2) C (Basic) - Salt of Strong Acid + Weak Base: pH = 7 - (1)/(2) pKb - (1)/(2) C (Acidic)

  • pH = 7 - (1)/(2) pKₐ - (1)/(2) C
  • pH = 7 - (1)/(2) pKₐ + (1)/(2) C
  • pH = 7 + (1)/(2) pKₐ + (1)/(2) C
  • pH = 7 + (1)/(2) pKₐ - (1)/(2) C
Show Solution

The Correct Option is C
