Which is not an example of common ion effect?

Options

  1. ANaCl + AgCl
  2. BH ₂ ~S + HCl
  3. CCH ₃ COOH + NaOH
  4. DNH ₄ OH + NH ₄ Cl

Correct answer

C. CH ₃ COOH + NaOH

Step-by-step solution

Common ion effect is the suppression of degree of dissociation of a weak electrolyte in the presence of a strong electrolyte having common ion. Among the given, CH ₃ COOH + NaOH has no common ion, thus does not exhibit common ion effect.
