Cоnsider the titrаtiоns оf the pаirs of аqueous acids and bases listed at the left. Which pair is incorrectly described (at the right) in terms of the acidic, basic or neutral character of the solutions ar the equivalence point? Acid-Base Pair Character at Equivalence Point (A) HClO + NaOH acidic (B) HNO 3 + Ca(OH) 2 neutral (C) CH 3COOH + KOH basic (D) HCl + NH 3 acidic (E) CH 3COOH + NH 3 neutral Hint: The conjugate base of a weak acid will hydrolyze water, similarly a conjugate acid of a weak base will hydrolyze water Example: HF + NaOH → H2O + F- + Na+; The F- is the conjugate base of the weak acid HF. The F- can react with water (hydrolysis) as shown below to produce OH- to make the equilibrium basic. F- + H2O → HF + OH-
