Formula and explanation
Weak acids (e.g., CH₃COOH) partially ionize in aqueous solution, establishing an ionization equilibrium. The expression for its ionization equilibrium constant Ka is: K a = (c(H⁺) · c(A⁻))/(c(HA)). Here, HA represents the weak acid molecule, and A⁻ is its conjugate base. A larger Ka value indicates stronger acidity.
