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. WebNov 22, 2015 · In the lecture sulfuric acid, H2SO4, was mentioned explicitly, because it is an exception to the rule. 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. showmybalance.com

WebThe first ionization of H2SO4 is complete. The second ionization is not complete, and has a Ka = 1.2X10^-2. If you are in a very low level chemistry class, you would generally just say that both ionizations are complete. That would make [H+] = 0.50 M. Then, pH = -log (0.50) = 0.30. But this is not true at all. WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H + ^+ + … WebJun 17, 2024 · 1 Answer. Sorted by: 11.
