Question

question 19
in response to a decreasing ph, the bicarbonate buffer system causes an increase in:
a free hydrogen ions (h+)
b carbonic acid (h2co3)
c bicarbonate ions (hco3)
d phosphoric acid (h2po4)
question 20
which of the following might contribute to respiratory acidosis?

Explanation:

The bicarbonate buffer system is \(H_2CO_3
ightleftharpoons H^+ + HCO_3^-\). When pH decreases (more \(H^+\) ions), according to Le - Chatelier's principle, the equilibrium shifts to the left. This means more \(H_2CO_3\) is formed.

Answer:

B. Carbonic acid (\(H_2CO_3\))
