Use the Henderson-Hasselbalch equation to calculate the pH of a buffer prepared by adding 10mL of acetic acid to 20mL of 0.10M sodium acetate (Ka= 1.75 x 10^5 for acetic acid).
Please showing working out, as am confused as to how to approach this question. Thanks in advance for your help.

pH = pKa + log [(base)/(acid)]
pKa = -log Ka
base = acetate
acid = acetic acid.
