WebbThe equilibrium concentration of hydronium ions is equal to 1.9 times 10 to negative third Molar. So we plug that in. And the initial concentration of our weak acid, which was acidic acid is 0.20 Molar. So the Molars cancel, and we get a percent ionization of 0.95%. Webb30 aug. 2015 · Since Ka is small compared with the initial concentration of the acid, you can approximate (0.20− x) with 0.20. This will give you Ka = x2 0.2 ⇒ x = √0.2 ⋅ 1.78 ⋅ 10−4 = 5.97 ⋅ 10−3 The concentration of the hydronium ions will thus be x = [H3O+] = 5.97 ⋅ 10−3M This means that the solution's pH will be pH sol = − log([H3O+])
