(a) initially (b) after the addition of 5.00 mL of HCl (c) after the addition of a total volume of 12.5 mL HCl (d) after the addition of a total volume of 25.0 mL of HCl (e) after the addition of 26.0 mL of HCl. show solution.​

Answer 1

Explanation:

A solution containing 50.00 mL of 0.1800 M NH3 (Kb = 1.77 x 10-5) is being titrated with 0.3600 M HCl. Calculate the pH: (a) initially (b) after the addition of 5.00 mL of HCl (c) after the addition of a total volume of 12.50 mL HCl (d) after the addition of a total volume of 25.00 mL of HCl (e) after the addition of 26.00 mL of HCl An example of the solution technique for part (a) is provided here. The answer for our example is 11.252.
