# 65 of 214 A2 equivalence 25.00 mL of a solution containing 0.1333 M ammonia (K = 1.76 x 10-5) is to be titrated with 0.1196 M HCI. NH3 + HCI → NH4CI Calculate pH at equivalence point. (Enter your answer to three significant figures. Ignore the dissociation of water.) Answer: #68 HOAc/NaOH preequivalence 25.00 mL of a solution containing 0.0984 M acetic acid (K₂ = 1.75 x 10-5) is to be titrated with 0.1272 M NaOH. CH3COOH + NaOH CH3COONa + H₂O Calculate pH after the addition of 13.8 mL of base. (Enter your answer to three significant figures. Ignore the dissociation of water.) Answer: pH Buffer 1 A buffer solution of pH 4.76 is to be prepared from acetic acid (with Ka = 1.80 x 10-5, sodium acetate and water. What must be the molar ratio of acetate ion to acetic acid in this solution to obtain this pH? Give your answer to 2 decimal places. Answer:
