WebbChemistry questions and answers. A buffer is made with sodium acetate ( CH3COONa ) and acetic acid ( CH3COOH ); the Ka for acetic acid is 1.80×10−5 . The pH of the buffer is 3.98. What is the ratio of the equilibrium concentration of sodium acetate to that of acetic acid if you assume that the Henderson-Hasselbalch equation is accurate? WebbCH3COOH (aq) + H2O (l) = CH3COO- (aq) + H3O+ (aq) CH3COOH is a weak acid, while CH3COO- is a weak base (the Na+ is not important to the buffer, it can be considered a spectator ion). The pH of this buffer depends on the [CH3COOH] and the [CH3COO-].
