Webbyou can enter the concentration of HNO 3 acid in mol dm -3 and check the pH value. Enter concentration of nitric acid in mol dm-3. Calculate pH. Answer. Note: This online calculation is not suitable for very dilute solutions of HNO 3 (such as 0.0000005 mol dm -3) because, those solutions give very low H + ion concentration. In those cases, pH ... Webb23 aug. 2024 · So you ignore the H^+ from the HCN. So HNO3 contribution is 0.1 M and that gives you a pH of 1.00. BTW, what is that M by Ka? Two points. First, Ka has no units. Some may argue with that but technically that is correct since Ka is derived from activity coefficients and those have no units. Second, even if you scrape units out of a Ka (using ...

Webb4 jan. 2016 · This means that the concentration of hydronium ions will be equal to that of the nitric acid. [H3O+] = [HNO3] = 0.01 M. As you know, a solution's pH is simply a measure of its concentration of hydronium ions. pH = −log([H3O+]) In this case, the pH of the solution will be. pH = −log(0.01) = 2. Answer link.
