Assume that you prepared a solution by adding 0.05mL ( 1 drop) of 0.5MHCl to 510 mL of "pure" water. Calculate the resultant pH. (1 mark) (Hint - the answer is not pH=9.3; add up the hydronium ions from ALL sources) EXPERIMENT P: TITRATION OF A WEAK ACID PRELAB ASSIGNMENT (CONTINUED) 5. In a titration, 25.18mL of a monoprotic weak acid HA (aq) is neutralized with 25.18mL of 0.502MNaOH(aq). Calculate the ratio of [A-] to [HA] after 12.59mL of the 0.502M NaOH (aq) had been added to the initial amount of HA(aq). ( 1 mark) (b) At the equivalence point, you have a solution of what salt? Explain briefly. ( 0.5 mark) 5. Refer to the titration curves for the strong acid HCl (Figure 1, p. P-2) and for the weak acid acetic acid (Figure 2, p. P-3). From the Table on p. P-5, select two acid-base indicators that would be suitable for replicate titrations of HCl with NaOH but would NOT be suitable for acetic acid with NaOH. (0.5 marks)
