The pH of which solutions do not change with dilution?

Options

  1. A1 M CH ₃ COONH ₄
  2. BCH ₃ COONa + CH ₃ COOH (Both 1 M each)
  3. CCH ₃ COOH + CH ₃ COONH ₄( Both 1 M each)
  4. D1 M CH ₃ COONa

Correct answer

C. CH ₃ COOH + CH ₃ COONH ₄( Both 1 M each)

Step-by-step solution

pH of CH ₃ COONa solution changes on dilution because it is a salt solution where as other are buffer solutions.
