Webb8 jan. 2016 · As you know, the pH of a solution is simply a measure of the concentration of hydronium ions. pH = −log([H3O+]) So, if you get one mole of hydronium ions for every one mole of hydrochloric acid, you can say that. [H3O+] = [HCl] = 0.001 M. This means that the pH of the solution will be. pH = −log(0.001) pH = 3. Answer link. WebbpH of any acid can be calculated by using the following formula: pH= -log (H+) Here H+ refers to the concentration of H+ ions or the Hydronium ions. Here it can be clearly observed that 1 moles of sulphuric acid gives rise to 2 moles of H+ ions. Therefore, 0.01 moles of H2SO4 will give rise to 0.02 moles of H+ ions. how to stay awake when tired all nighter
