If an acid were added to the buffer pair H₂CO₃-NaHCO₂, the concentration of NaHCO₃ would drop.

Question

Quizplus · Accepted Answer

The H₂CO₃ and NaHCO₂ buffer pair is functioning to maintain a stable pH by accepting or donating H+ ions, depending on their availability in the solution. If an acid is added, it would increase the concentration of H+ ions in the solution, and the buffer would react by donating H+ ions, which would result in a decrease in the concentration of NaHCO₃.
