WebKnowing the [H⁺], we can calculate the pH as follows: pH = -log [H⁺] Consider the first case, [HCl] = 0.1 M. Hence, [H⁺] = [HCl] = 0.1 M. So, the pH can be calculated as follows: pH = -log [H⁺] = -log(0.1) = 1. Hence the pH of 0.1 M HCl will be 1.---Consider the second case, [HCl] = 0.01 M. Hence, [H⁺] = [HCl] = 0.01 M. So, the pH can ... WebHCl pKa=-10 c=0.1 Case 2. Solution is formed by mixing known volumes of solutions with known concentrations.

WebDec 10, 2014 · After adding 80.0 mL of 0.100 mol/L HCl, you have in solution (0.00800 -0.00400) mol = 0.00400 mol of H₃O⁺. The total volume of the solution is (40.0 + 80.0) mL = 120.0 mL = 0.1200 L. [H₃O⁺] = 0.00400 mol/0.1200 L = 0.0333 mol/L pH = -log [H₃O⁺] = -log (0.0333) = 1.48 ( 21 votes) Show more... Salvatore Argentieri 8 years ago WebWe will calculate the pH of 25 mL of 0.1 M HCl titrated with 0.1 M NaOH. At each point in the titration curve, we will need to determine two quantities, the concentration of H + remaining in the solution, and the volume of the solution. From these, we can calculate the [H +] and, from that, the pH. 1.
WebThe solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution … WebJan 30, 2024 · 0.00025 M HCl, HCl is a strong acid [H 3 O +] = 2.5 X 10 -4 M pH = -\log (2.5 X 10 -4) = 3.6 Then solve for the pOH: pH + pOH = 14 pOH = 14 - pH pOH = 14 - 3.6 = 10.4 3. Use the pOH equation pH = − log[OH −] and pK w equation pKw = pH + pOH = 14. 0.0035 M LiOH, LiOH is a strong base [OH -] = 3.5 X 10 -3 pOH = -\log (3.5 X 10 -3) = 2.46
