In the reaction HC₂H₃O₂ ⇌ H⁺ + C₂H₃O₂^- , if [HC₂H₃O₂] = 1.0 × 10^-6 M and the pH = 4.0, what will K be?

Question

Quizplus · Accepted Answer

Given the reaction and the conditions (pH = 4.0, meaning [H+] = 10^-4 M), the equilibrium constant (K) calculation involves the concentration of reactants and products. The provided information indicates a reaction involving hydrogen ions, suggesting that the pH (and thus [H+]) plays a crucial role in the equilibrium. The correct answer involves understanding the relationship between pH, [H+], and the equilibrium constant for reactions involving acids or bases. In this case, the equilibrium constant is affected by the concentration of hydrogen ions, which is derived from the given pH. The calculation would involve the concentrations of all species at equilibrium, but the specific details provided lead to the conclusion that K = 0.01, considering the pH and the concentration of the initial substance.
