Not exactly sure what the question is asking, but sodium acetate will not buffer at pH 8. It is an ok buffer in the pH range of maybe 3-5 or so. Acetic acid is the weak acid of this buffer with a pKa near 10^-5. To make a decent buffer at pH 8, one needs a weak base, or a weak acid with a pKa closer to 8.
