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 acetic acid (0.048 M) by the ionization percentage (5.2%), which gives 0.048 M * 0.052 = 2.5 × 10⁻³ M.
