If anyone could kindly explain how to do these.... Any help is appreciated with the following problems!! Thanks in advance

Case study: HA with a pKa = 5.0 (i.e. Ka = 10 -5)

Class 1 acid (HA) only

What is the pH of a 0.01 M solution of this weak acid HA?

[HA] = 10 -2, >> Ka =10 -5)

Class 2 base (A-) only

What is the pH of a 0.01 M solution of NaA?

Class 3 acid & base forms.

What is the pH of a solution containing 0.02M HA and 0.01M A-?

    can someone please help me out with questions 1-5, please To add more information this was given to me for a lab that used a weak acid and we added a strong base through titration. We just observed how the ph changes. Later we then used a buffer with a weak acid to see how buffers affect ph change. These questions are basically surrounded around those topics to help us prepare. However, I'm kinda confused about answering them because weak...

    a) A solution contains 0.34 M of a weak acid HA (Ka = 2.0 x 10-7) and 0.17 M NaA. What is the pH after 0.05 M of HCl is added to this solution (assume no volume change) b) The pH of a solution containing 0.1 M of a weak acid HA is 6. Calculate Ka for this acid. Note the acids are unrelated for the two problem parts.
