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 29.80 mL of 0.0567 M NaOH to reach the equivalence point?
◦ 0.0567 M
◦ 0.0476 M
◦ 0.0134 M
◦ 0.0676 M

Question 2
