3. If the Ka for the weak acid, HA, is 2.40 x 106, what is the pH of 0.0750 M solution of HA? Answer: 5. 6. If the acid dissociation constant for formic acid, HCOOH, is 1.74 x 10-4, what is the molar concentration of formate, HCOO", in a solution containing 150.0 μM H* and 35.0 µM formic acid? Answer: Determine the concentration ratio of acetate to acetic acid when the pH of the acetic acid plus acetate solution is 5.45 and the K₂ of acetic acid is 1.81 x 10-5. 3.
