Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
H2CO3 is not used as buffer.
A buffer solution is one involving a weak base/weak acid with its conjugate acid/base. In a buffer solution, the pH must be changed to only a small amount. Thus, any solution with a STRONG acid or a STRONG base is not a successful buffer solution because there would be a relatively large change in the initial pH.
There are many places where one can find information about buffer solution. One can find information about buffer solution at popular on the web sources such as Chem Guide and Doc Brown.
Add a base or a buffer into the solution.
The pH lowers. Just as with any other solution.
Sodium carbonate and and sodium hydrogen carbonate form a buffer solution.

Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
a solution which does not fulfills the property of a buffer solution but act as buffer solution.

The buffer can keep the pH stable when small amounts of acid or base are added. - NOVA
The mixture Na2CO3 + NaHCO3 is a buffer in the range 9,2-10,8 pH.
If the solution is not a buffer, the HCl will react with the solution to form a product.
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
