Question

What is the hydronium ion concentration of a 0.010 M solution of acetic acid? K_a for acetic acid is 1.8 *10^-⁵.

Quizplus · Accepted Answer

The hydronium ion concentration can be calculated using the formula for weak acid dissociation: [H₃O⁺] = √(Kₐ × [HA]). Substituting the given values: [H₃O⁺] = √(1.8 × 10⁻⁵ × 0.010) = √(1.8 × 10⁻⁷) ≈ 4.2 × 10⁻⁴ M.
