Posted by Maddie on Friday, April 12, 2013 at 12:46pm.

The pH of an 0.0870 M solution of weak acid A is 2.20. The pH of an 0.0830 M solution of weak acid B is 4.07. The pH of an 0.0890 M solution of weak acid C is 5.13. Identify the three acids from among those listed below (the Ka values are listed in Appendix E of your textbook).
A H3BO3
B CH3CO2H
C HClO
D HCO2H
E H2S
F C6H5CO2H
G HNO2
H HCN
I HF
J None of the above

I'm not exactly sure what to do with the molarities... Any help please?
