Question:
“Buffer capacity” is defined as the amount of either acid or base needed to cause a change of one pH unit for 1.0 L of buffer solution. For a buffer solution prepared from acetic acid (CH3COOH) and sodium acetate (CH3COONa), how much would the concentrations of acetic acid and/or acetate ion have to change (i.e., as a result of added acid or base) in order for the pH of 1.0 L of the buffer solution to change by one pH unit? Explain your reasoning. You should use any appropriate chemical and/or mathematical equations to substantiate your arguments. CH3COOH(aq) + H2O(l) ⇌ H3O+ (aq) + CH3COO- (aq)
