WebFeb 3, 2024 · Table of Common Ka Values for Weak Acids. K a is the equilibrium constant for the dissociation reaction of a weak acid. A weak acid is one that only partially dissociates in water or an aqueous solution. The value of K a is used to calculate the pH of weak acids. The pK a value is used to choose a buffer when needed. WebApr 19, 2024 · Let's "calculate" [H +] for the first proton, [H +] = [H 2SO4] = 0.325M. and work this in to our second proton dissociation calculation, Ka2 = x(0.325 + x) 0.325 − x = 1.2 ⋅ 10−2. ∴ x = 0.0112. Hence, the pH of our solution is approximately, pH = −log(0.325 +x) ≈ 0.473. which is reasonable because sulfuric acid is a very strong acid.
