Q. In our body, carbon dioxide

({C O}_{2})

combines with water

(H_{2} O)

to form carbonic acid.

H_{2} O + {C O}_{2} ⟶ H_{2} {C O}_{3}

Carbonic acid undergoes dissociation as,

H_{2} {C O}_{3} ⇌ H^{+} + H {C O}_{3}^{-}

During the physical and mental stress, the rate of respiration increases, which results in the decrease in concentration of

{C O}_{2}

in the blood. What will be the effect on pH of human blood during the stress?
