Question
Formic acid (HCO2H, Ka = 1.8 x 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? Answer 0.0134 M 0.0476 M 0.0567 M 0.0676 M Formic acid (HCO2H, Ka = 1.8 x 10-4) is the principal component in the venom of stinging ants.

25 x M = 29.8 x 0.0567
=> M = 0.0676 M
