Using the sketch in Exercise 61 as a guide, sketch the molecular view of a solution in which

(a) HCl(aq) is titrated to the equivalence point with KOH(aq)

(b) CH₃COOH(aq) is titrated halfway to the equivalence point with NaOH(aq).

Exercise 61

Which of the following points in a titration is represented by the molecular view shown in the sketch?

(a) 20% of the necessary titrant added in the titration of NH₄Cl(aq) with HCl(aq)

(b) 20% of the necessary titrant added in the titration of NH₃(aq) with HCl(aq)

(c) The equivalence point in the titration of NH₃(aq) with HCl(aq)

(d) 120% of the necessary titrant added in the titration of NH₃(aq) with HCl(aq).
