How does a mixture of a weak acid and its conjugate base help buffer a solution against pH changes? If we mix a weak acid (HA) with its conjugate base (A-), both the acid and base components remain present in the solution.This is because they do not undergo any reactions that significantly alter their concentrations.

67 PREPARATION AND TESTING OF BUFFER SOLUTIONS. P. URPOSE. The purpose of the laboratory investigation is to experimentally determine (1) pKa (and thus Ka) of the acid in a buffer and thus the buffer range, (2) investigate the buffer capacity of Buffer Solutions. A buffer solution is one in which the pH of the solution is "resistant" to small additions of either a strong acid or strong base. Buffers usually consist of a weak acid and its conjugate base, in relatively equal and "large" quantities. Calculations are based on the equation for the ionization of the weak acid in water

So, a buffer solution can be defined as a solution which resists a change in its pH when such a change is caused by the addition of a small amount of acid or base.. This does not mean that the pH of the buffer solution does not change (we make this assumption while doing numerical problems). It only means that the change in pH would be less than the pH that would have вЂ¦ BUFFER SOLUTIONS - INTRODUCTION AND USES Definition вЂњSolutions which resist changes in pH when small quantities of acid or alkali are added.вЂќ Types Acidic Buffer (pH < 7) weak acid + its sodium or potassium salt ethanoic acid sodium ethanoate вЂ¦
