Question 1

Formic acid (HCO2H, Ka = 1.8 × 10-4) is the principal component in the venom of stinging ants. What is the molarity of a formic acid solution if 25.00 mL of the formic acid solution requires 44.80 mL of 0.0567 M NaOH to reach the equivalence point?
◦ 0.0134 M
◦ 0.0316 M
◦ 0.102 M
◦ 0.0567 M

Question 2

What is the pH of the resulting solution if 40.00 mL of 0.10 M acetic acid is added to 10.00 mL of 0.10 M NaOH? Assume that the volumes of the solutions are additive. Ka = 1.8 × 10-5 for CH3CO2H
◦ 8.78
