Help with Acid and Base hydrolysis reactions

Hi I was wondering if I could have help with the following equations, to what the following acid and base relating to the equations are;
0.1M NaHSO4+H20
and
Na2HPO4+H20

Thank you :) ;D

Sorry, I'm a little confused..
Are you asking which is an acid and which is a base, or..?

I'm not entirely sure what you're asking but here are the relevant equations:
NaHSO4+H2O ----> Na+ + HSO4-
Where NaHSO4 dissociates in water to become a sodium ion and hydrogen sulfate ion. Note that NaHSO4 cannot act as an acid or a base here. However, the HSO4- can act as a base and accept another proton to become sulfuric acid or it could dissociate further into H+ and SO42-

and

Na2HPO4 + H2O ----> 2Na+ + HPO42-
Another dissociation equation, where similarly HPO42- can either dissociate again or act as a base to accept up to two protons.
I hope this cleared up whatever issues you were having. I left out states intentionally for simplicity but don't ever forget them when you're writing in any assessment.
