Answer:

No

Explanation:

A buffer solution is a combination of a weak acid and its conjugate base; for instance, carbonic acid (H2CO3) and sodium bicarbonate (NaHCO3), not sodium carbonate (Na2CO3). Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications.
