When values of K_a are small (e.g., 1 *10^-⁵) and concentrations of weak acids [HA] are relatively large (e.g., 0.10 M), the hydronium ion concentration of the solution can be calculated using which expression?

Question

Quizplus · Accepted Answer

For weak acids, the hydronium ion concentration can be approximated using [H⁺] = (Kₐ[HA])^1/2 when Kₐ is small and [HA] is relatively large.
