What kind of buffer would be a mixture of CH3COOH and CH3COONa?

acidic buffer

A mixture of a weak acid and its salt with a strong base serves as an acidic buffer. The reaction shows that some acetic acids react with the OH– from the base and converts it to water.

Which of the following is not a buffer solution CH3COOH CH3COONa?
