Formic acid (HCOOH) is a weak acid used as preservative and antibacterial agent in livestock feed. Which of the following aqueous solutions of HCOOH has the highest%dissociation in aqueous solution? The K, for HIO is 1.8x 10- 4 at 25C. Hint: this question does not necessarily need any math to be answered. O a. 1.2103MHCOOH Ob. 4,510 MHCOOH O c. all have the same %dissociation because all have the same K d. 7810 MHCOOH
