WebApr 4, 2024 · We have that the pH of the solution derived to be. From the Question we are told that. Mass of CH3COONa=1.60g. Volume of CH3COONa v=40ml. 0.10 M acetic acid. Ka of CH3COOH is 1.75 × 10^-5. Generally the equation for the pH is mathematically given as. Where. Generally. And. Therefore returning to the initial pH equation. In conclusion WebAug 30, 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+])
