Calculate the pH during the titration of 20.00 mL of 0.1000 M trimethylamine, (CH3)3N(aq), with 0.2000 M HClO4(aq) after 9.48 mL of the acid have been added.

Complete Question

Calculate the pH during the titration of 20.00 mL of 0.1000 M trimethylamine, (CH3)3N(aq), with 0.2000 M HClO4(aq) after 9.48 mL of the acid have been added.Kb of trimethylamine = 6.5 x 10-5.

The pH is    

Explanation:

From  the question we are told that

   The  volume of trimethylamine, (CH3)3N(aq) is

    The concentration of trimethylamine is  

    The  volume of HClO4(aq) is

    The  concentration of  HClO4(aq) is  

      The Kb  value is  

Generally the the pOH of this reaction is mathematically represented as

Here is the number of moles of acid which is evaluated as

=>
