Question- Calculate the equilibrium pH using BOTH the equilibrium approach and Henderson Hasselbalch equation approach for an acetate buffer solution that consists of 0.10M acetic acid (CH3COOH) and 0.15M sodium acetate (CH3COONa). Please show all your work. Do the two methods agree with each other? Ka of acetic acid = 1.8 x 10^-5
