Web(1.00 M CH3COOH)(200.0 mL)(1 L/1000 mL) = 0.200 mol CH3COOH (10.0 g NaCH3COO)(1 mol/82.03 g) = 0.122 mol NaCH3COO Substitute these values, along with the Kavalue, into the above equation and solve for the hydronium ion concentration. Convert the hydronium ion concentration into pH. [H3O+] = (1.7 x 10-5)(0.200/0.122) = 2.79 x 10-5 pH = 4.56 Web*The pH of the solution is close to 2. At equivalence point: *The pH changes most rapidly. *The pH of the solution is 7. After equivalence point: *The pH of the solution is close to 12. *The color of the solution is pink. A volume of 100 mL of 1.00 M HCl solution is titrated with 1.00 M NaOH solution.
WebWhen HCl concentration is too low like 0.00000001, 0.000000001 mol dm -3, pH value is not effected very much due to dilution of HCl acid. If HCl concentration is very low, pH value is …
WebApr 23, 2024 · pH = 1.10 Explanation: First thing first, calculate the total volume of the resulting solution V total = 100.0 mL + 50.0 mL + 100.0 mL V total = 250.0 mL Now, you are dealing with two strong acids that ionize completely in aqueous solution.
