Which of the following is a volatile acid of physiologic significance?

Question

Quizplus · Accepted Answer

Carbonic acid is a volatile acid of physiologic significance because it is involved in the control of blood pH through the respiratory system. When carbon dioxide is breathed out, it reduces the amount of carbonic acid in the blood, which raises the pH. Conversely, when carbon dioxide is retained, there is an increase in carbonic acid and a decrease in pH. Hydrochloric acid and phosphoric acid are non-volatile acids. Lactic acid is a product of anaerobic metabolism and can contribute to acidosis, but it is not a volatile acid.
