Best Answer

The carbonic acid-hydrogencarbonate buffer system. Carbonic acid, H2CO3, acts as the weak acid and hydrogencarbonate, HCO3-, acts as the conjugate base. An increase in H+ ions in the blood is removed by the hydrogencarbonate conjugate base. As the H+ ions are increased, the conjugate base reacts with the H+ ions which causes the position of the equilibrim to shift to the left, which removes most of the added H+ ions. On the other hand, an increase in the OH- ions in the blood is removed by the weak acid. As the OH- ions increase, the small concentration of H+ ions react with the OH- ions which causes the acid to dissociate and pushes the position of the equilibrium to the right to restore most of the H+ ions that have reacted.

A solution called a pH buffer prevents a solution from changing it's pH. pH buffers usually come in tablet form, for different pH's, which you drop into a certain amount of water to make that pH.

This is called a buffer system. It resists changes in [H+] concentration, which is the same as saying it resists changes in pH.

What happens to the buffer solution pH 7 when acid is added?

When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.


Do buffers resist change in pH?

Yes.


What is true about buffer solutions?

They maintain a relatively constant pH when acids or bases are added. Buffers are substances that minimize changes in the concentrations of H+ and OH- in a solution. Buffers do so by accepting hydrogen ions from the solution when they are in excess and donating hydrogen ions to the solution when they have been depleted.


Why does a solution of a conjugate acid base pair behave as a buffered solution?

The resist pH change in the following way: If you add a strong acid to the buffer solution, the conjugate base gets protonated, but the pH is not significantly changed. If you add a strong base to the buffer, the conjugate acid gets deprotonated, and again the pH is not changed very much. If you only had one component (let's say just the conjugate base), then it would not be able to resist change in pH if you added a strong base to the solution (although it would still counteract the affect of added acid).
