Dear Jane Thank You
There is a mechanical error in the 5th line of the solution, after, "we get:". The molar concentration is c=0.40 according to the question but, in this line it was written as c=0.04. This alters the final answer from pH=2.07 to pH=2.57. Other then this the question is answered well.
