Consider a flask containing 50.00 ml. of 0.0426 M trimethylamine ((CH,),NH,). This is titrated with a 0.0957 M hydrochloric acid solution from a burette. Given: K, of (CH,), NH, is 6.5 x 10-5, 1.1 Determine the pH of the solution in the flask after 28.00 mlL of the acid has been added? You must show any reaction equation(s) that you may think are necessary. 1.2 Determine the pH of the solution in the flask at the half-way point of the titration.
