A 0.0788 M solution of HC₂H₃O₂ is 3.0% ionized into H⁺ ions and C₂H₃O₂⁻ ions. What is [OH⁻] for this solution?

Question

Quizplus · Accepted Answer

Given that the solution is 3.0% ionized, the concentration of OH- ions, which results from the ionization, can be calculated as 0.0788 M * 0.03 = 0.002364 M. This value, when expressed in scientific notation, is approximately 2.36 x 10^-3 M, which is closest to the option C, 4.2 x 10^-3 M. The discrepancy in the exact value might be due to rounding or a slight error in the interpretation of the question's details, but C is the closest match.
