Which of the following is not a property of a buffer solution? a) It is a mixture of a weak acid and its conjugate base. b) Resists pH changes because it reacts with added acid or base. c) The maximum buffer capacity is at pH = pKa. d) pH is dependent on the solution ionic strength and temperature. e) pH is independent of concentration.

a) It is a mixture of a weak acid and its conjugate base. TRUE. A buffer is defined as a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid.

b) Resists pH changes because it reacts with added acid or base. TRUE. Thermodynamically, the reaction of added acid or base is faster with the buffer mixture than with H⁺ or OH⁻ ions of the solutions.

c) The maximum buffer capacity is at pH = pKa. TRUE. The buffer capacity is pka±1. For this, buffer capacity is maximum in pka.

d) pH is dependent on the solution ionic strength and temperature. TRUE. Ionic strength and temperature are factors that influence concentrations of ions in solutions as the H⁺ ion that is the responsible

e) pH is independent of concentration. FALSE. pH in a buffer depends completely of concentrations of the acid and its conjugate base or vice versa.

I hope it helps!

The option 'pH is independent of concentration' does NOT indicate a property of a buffer solution.

What is a buffer solution?

A buffer solution is a solution capable of resisting modifications in the concentration of protons (pH) after acid/alkali addition.

A buffer solution is sensitive to the amount of acid/alkali that is added to the solution.

In conclusion, the option 'pH is independent of concentration' does NOT indicate a property of a buffer solution.
