Buffer capacity ((): for a weak acid and conjugate base pair, the buffer capacity is defined as the concentration of the salt (conjugate base) divided by that of the acid. In practice, and in a case like that of the weak acid and its conjugate base example, the buffer capacity is defined as the moles/litre of a strong base that need to be added ...

Conjugate acid-base pairs. Returning to equation (1) above, the species left after an acid has dissociated (NO 3 – in this example) is called the CONJUGATE BASE of the acid. A conjugate acid/base pair are any two species +that differ in formula by a single H . Similarly, as the difference between the formulas H 2 O and H 3

In the exercise, Bronsted-Lowry Acids and Bases, it was shown that after on acid has given up its proton, it is capable of getting back that proton and acting as a base, conjugate base is what is left after an acid gives up a proton. The stronger the acid, the weaker the conjugate base. The weaker the acid, the stronger the conjugate base.

The conjugate base of acetic acid is referred to as acetate (usually the sodium ion is used), CH3COO-. At the pKa there is an equal amount of the acid form (acetic acid, CH3COOH) and the base, (acetate CH3COO-). At pHs on the acid side of the pKa i.e. < 4.7 there will be more acid form than base form.

The buffer, composed of a weak acid (HA) and its conjugate base (A-), is chosen to provide maximal buffering capacity at a given pH. The calculation of the quantity of each buffer component needed to achieve the desired pH is determined by use of the Henderson-Hasselbach equation: (2.4.1) p H = p K a + log. .
