WebHydronium Ion. At lower pH the hydronium ions (H3O+) available in water protonates the functional groups of melanin and at pH greater than 4, there is a dip in the concentration of hydronium ions leading to the development of negative charge in the functional groups of melanin. From: Inorganic Pollutants in Water, 2024. WebJan 8, 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.
