I think 2 is ok.
For #1, I agree this is an approximate number. Frankly, I don't know what an approximate pH is. It probably means ignoring k2 for H2SO4; if so then the 2.5 is fine.
1) The approximate pH of a 3.0 X 10^-3 M solution of the strong acid H2SO4 is?
I did pH= -log(3.0 X 10^-3) = 2.5
2)If HCLO2 is a stronger acid than HF, which is stronger than HOCL, then the order of strengths of the conjugate bases of these acids is?
My answer is CLO2^-^ < F^-^ < CLO^-^ because the weaker the acid, the stronger its base. HOCL is the weakest acid so its base would be the strongest.
Would you agree with my answers? Thank you!
