Explanation / Answer

This can be answered on the basis of the Le Chatelier principle which states that the reaction will always move in the direction in which it can attain equilibrium. Thus,

19. If too many H+ ions are present in the body, the reaction will love towards the left I.e. make more H2CO3 so as to maintain a state if equilibrium and prevent acidosis.

Similarly, if too few H+ ions are present, the reaction will move towards right- more H+ ions will be produced in an attempt to restore the equilibrium.

20. ( a and d) pH buffers basically help in maintaining the pH of the solution is stabilize it. They convert string acids or bases into weak ones.
