Question 1

What is the [H3O+] of an aqueous solution measured to be 0.20 M in sodium acetate and 0.40 M in acetic acid? (Ka = 1.8 × 10-5)
◦ 1.8 × 10-5 M
◦ 9.0 × 10-6 M
◦ 3.6 × 10-5 M
◦ 7.2 × 10-5 M
◦ 4.7 M

Question 2

What is the approximate pH at the equivalence point of a weak acid-strong base titration if 25 mL of aqueous formic acid (HCOOH) requires 29.80 mL of 0.3567 mol L-1 NaOH(aq)? Ka =1.8 × 10-4for formic acid.
◦ 2.06
◦ 5.48
◦ 8.52
◦ 11.94
