Question 1

Calculate the [H+] in a solution that is 0.20 M in NaF and 0.25 M in HF. (Ka = 7.2 × 10–4)

◦ 7.2 × 10–4M
◦ 1.2 M
◦ 9.0 × 10–4M
◦ 0.20 M
◦ 5.8 × 10–4M

Question 2

Calculate the pH at the equivalence point for the titration of 1.0 M ethylamine, C2H5NH2, by 1.0 M perchloric acid, HClO4. (pKb for C2H5NH2 = 3.25)

◦ 6.05
◦ 2.24
◦ 5.53
◦ 2.09
◦ 5.38
