WebAug 29, 2024 · Solution: The concentration can be calculated by dividing the amount of solute by the volume of solution [Eq. 3.11.1 ]: c KI = n KI, mol V solution, L. We obtain n KI from the mass of KI added to the flask: m KI = 43.2874 − 30.1544 g = 13.1330 g. n KI = 13.1330 g × 1 mol 166 .00 g = 7.9115 × 10 − 2 mol. 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
