Question
Fear or excitement, generally cause one to breathe rapidly and it results in the decrease of concentration of CO2 in blood. In what way, it will change the pH of blood?
Options
A.pH will increase
B.pH will decrease
C.No change
D.pH becomes 7.0
Solution
$\underset{\underset{\text{Decrease}}{\downarrow}}{Co_{2}} + H_{2}O\overset{\leftleftarrows}{\quad\begin{aligned} & \leftarrow \\ & \text{Shift left} \end{aligned}\quad}HCo_{3}^{-} + H^{+}$
As [H+] decreases, PH increases.
