Question:

The Henderson–Hasselbalch equation can be written as

08(21/1 -1) pH = pKa - log where a [A] [A] + [HA]

Thus, the degree of ionization (α) of an acid can be determined if both the pH of the solution and the pK_aof the acid are known.

(a) Use this equation to plot the pH versus the degree of ionization for the second ionization constant of phosphoric acid (K_a = 6.3 x 10^-8).

(b) If pH = pK_a what is the degree of ionization?
