Question

Which of the following combines with water to form carbonic acid .​

a) CO2
b) C
c) HCl
d) K​

Answer 1

Answer:

In our body following ionic equilibrium are present.

H

2

O+CO

2

⇌H

2

CO

3

⟶(i)

H

2

CO

3

⇌H

+

+HCO

3

−

⟶(ii)

If rate of respiration increases, the concentration of CO

2

decreases in the blood. As a result concentration of H

2

CO

3

(carbonic acid) also decreases according equation 1. Now H

2

CO

3

/HCO

3

−

system acts on buffer. So to maintain equilibrium (ii) more concentration of H

+

will be needed. As a result pH decreases.
