Question

Quizplus · Accepted Answer

When carbon dioxide content increases, it forms carbonic acid which dissociates into hydrogen ions and bicarbonate ions. This leads to an increase in acidity, resulting in a decrease in pH. On the other hand, when carbon dioxide content decreases, there is less formation of carbonic acid which leads to a decrease in hydrogen ions and an increase in pH. Therefore, the pH of body fluids will be less when the carbon dioxide content increases compared to when it decreases.
