Best Answer

A buffer is a substance in a solution that releases and captures hydrogen ions, keeping the pH the same.
Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change
A buffer resists change in pH by accepting hydrogen ions when acids are added to the solution and donating hydrogen ions when bases are added.
