In our body, CO2 combines with water to give H2CO3, and this dissociates to H+ and HCO3- and this causes the pH of the blood to fall in acidic range. This acidified blood acts on our own cells leads to degeneration of cells. Hence we feel tired during playing. This is the process of dehydration. When we feel thirsty and tired after playing, what we have to do is to just cover your nose and mouth, and inhale the gas which you exhaled, leads to the reversal of reaction and balances our blood pH.

Just I want to share this info with others and it went as big para. Sorry.

A buffer is a solution that can resist changes in its pH when an acid or base is added to it. Buffers typically consist of a weak acid and its corresponding conjugate base (or a weak base and its corresponding conjugate acid).

These components work together to neutralize the added acid or base, helping to maintain the solution's pH at a relatively constant level. Buffers play a crucial role in biological systems, such as blood, where maintaining a stable pH is essential for proper functioning.

In this system, carbon dioxide (CO2) combines with water to form carbonic acid (H2CO3), which in turn rapidly dissociates to form hydrogen ions and bicarbonate (HCO3- ). The carbon dioxide - carbonic acid equilibrium is catalyzed by the enzyme carbonic anhydrase; the carbonic acid - bicarbonate equilibrium is simple proton dissociation/association and needs no catalyst.

The Buffer Solution is Applicable for Weak acid & Weak base so H2CO3 is a Weak acid Because.

How to form an h2co3? Carbon dioxide is reacting with a water molecule to form an Carbonic acid this an.

Weak acid so Present in human Blood this Acid Main part of the Buffer System in Blood.

A buffer solution is a solution which a resistible change in ph upon adding a small amount of acid or base. The h2co3 is to maintain the ph value of the body.

Since the acidity content of the body is too high, the bicarbonate maintains ph by neutralizing it.

The human blood pH contain 5.7 in acidic condition for maintained by the presence of air in H2Co3-HCo3 as act as buffer of the maintain the pH of the human body system.

First up all I would like to say buffer solution is weak acid or base and their salts so here we have HCOOH and its salt HCOO.

So the first one is correct.

Yes A, it's because of the weak acid so that present in human blood, and the acid main part of the buffer system in blood, that is why A is the answer.

H2co3-Hco3 are to maintain pH due to it stabalies the acid.

The acid is always high in the bodywhich is nutralise by bicarbonate.

I do not understand properly. I am the student of grade 10 please make me clear about it in a simple way.
