Question 6 0.1 pts Consider a titration of formic acid (HCOOH, K2 = 1.8 x 10-4) with NaOH. The experiment is halted when half of the acid has been titrated. Which statement correctly describes the composition of the titration solution? Check all that apply. The concentrations of HCOOH and H+ are equal. The concentration of HCOOH is greater than the concentration of H+. The concentration of formate ions (HCOO-) is smaller than the concentration of H+. The concentration of HCOO-is...
Consider a titration of formic acid (HCOOH, Ka = 1.8 x 10-4) with NaOH. The experiment is halted when half of the acid has been titrated. Which statement correctly describes the composition of the titration solution? Check all that apply. Group of answer choices The concentration of HCOOH is greater than the concentration of H+. The concentration of HCOO− is approximately equal to the concentration of HCOOH. The concentration of formate ions (HCOO−) is smaller than the concentration of H+....
