The Ka1 value on its own is large, and the Ka2 value is 10^-2 which by itself is also significant in the equilibrium. As such, unlike most other acids with multiple Hydrogens, sulfuric acid has a high Ka2 which makes it strong. 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. right cars houston
