Quick Buffer Question

Hey guys. Was just wondering whether anyone could help me out with a chem question.

"Aqueous solutions of acetic acid contain both an acid and a base. Can the acetic acid solution alone be considered a buffer?"

If anyone could give me some information on both this, and how conj. pairs actually work it would be very appreciated.

 

Buffers are things that prevent the pH of a substance from changing or keeping it close to neutral or what it needs to be to function.

 

My test is tomorrow. I think i've got this down.
Thanks for the advice Gold
