Consider the weak acid CH₃COOH (acetic acid). If a 0.048 M CH₃COOH solution is 5.2% ionized, determine the [H₃O⁺] concentration at equilibrium. A) 0.25 M B) 9.2 * 10^-3 M C) 0.048 M D) 0.052 M E) 2.5 * 10^-3 M

Question

Quizplus · Accepted Answer

The [H₃O⁺] concentration is calculated by multiplying the initial concentration of CH₃COOH (0.048 M) by the ionization percentage (5.2%), which gives 0.048 M * 0.052 = 2.5 * 10^-3 M.
