Why would the pH of your blood plasma increase if you breathe fast?

When you exhale, you release carbon dioxide, which is a waste product. Normally, the respiratory system keeps these two gases in balance. Respiratory alkalosis occurs when you breathe too fast or too deep and carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline.

Why would the pH of your blood plasma increase if you breathe fast? If you breathe fast, CO2 is expelled and the equilibrium shifts to lower[H3O+], which raises the pH.
