Learn about the bicarbonate buffer system. Understand how carbonic acid and bicarbonate buffer the pH system in blood and see the equation for this reaction.

If a buffer solution contains 0.200 M formic acid (p K a = 3.75) and 0.200 M sodium formate, what is the pH of this solution?

What Is a Buffer Solution? A buffer is a solution that resists changes in pH due to its composition of either a weak acid and its conjugate base or a weak base and its conjugate acid.

A weak base will not completely dissociate in an aqueous solution. It can also be used in buffers to help keep pH levels constant as strong bases or acids are introduced to the solution.
