can you help me answer 1-4

1. Using the Ka 's for HC2H3O2 and HCO3 - (from Appendix G), calculate the K6 's for the C2H3O2 - and CO32 ions. Compare these values with those calculated from your measured pH's. 2. Using K3 for NH3 (from Appendix H ), calculate K2 for the NH4+ion. Compare this value with that calculated from your measured pH. 3. How should the pH of a 0.1M solution of NaC2H3O2 compare with that of a 0.1M solution of KC2H3O2 ? Explain briefly. 4. What is the greatest source of error in this experiment? How could you minimize this source of error? 1. Using the Ka 's for HC2H3O2 and HCO3 - (from Appendix G), calculate the K6 's for the C2H3O2 - and CO32 ions.
