Question 1

What is the pH of a solution prepared by mixing 100.00 mL of 0.025 M Ca(OH)2 with 50.00 mL of 0.080 M LiOH? Assume that the volumes are additive.
◦ 13.25
◦ 12.67
◦ 12.78
◦ 12.95

Question 2

What is the hydronium ion concentration of a 0.300 M acetic acid solution with Ka = 1.8 × 10-5? The equation for the dissociation of acetic acid is:

CH3CO2H(aq) + H2O(l) ⇌ H3O+(aq) + CH3CO2-(aq).


◦ 4.2 × 10-2 M
◦ 2.3 × 10-2 M
◦ 4.2 × 10-3 M
◦ 2.3 × 10-3 M
