Please Help a) Calculate the pH of a solution initially 0.1 M in acetic acid and 0.02 M in sodium acetate. The pKa for acetic acid is 4.76. B) calculate the pH of the buffer if you add 10 ml of 0.1 M HCL to 100ml of the buffer in part a.
Homework Answers
As this is a buffer solution we can calculate the pH by using Henderson Hasselbach equation.
For the 2nd part we have to calculate the new concentration of the acid and salt after adding strong acid HCl.
The solution is given below.
