A curious student who enjoys B/L A/B rxn obtains a beaker containing DI water and simultaneously adds?
0.1 mol Na2O (s), 0.05 mol Na2S (s), 0.04 mol H4nHSO4 (s) and 0.15 mol of (H4N)2SO4 (s) and .05 mol (HO)2SO2 (l). adds water till volume is 1L.
1. Write the eqn for each rxn which occured in strength order
2. Expect for H2O write a complete correct quantitative prinicipal species inventory for the resulting system
3. calculate the [H3O+] for the resulting system. pH is between 8-10
4. Now calculate the amount of moles of NaHSO4(s) to be dissolved in the system to lower the pH to 2.40. Include the rxn equations that take place.
5. Write an eqn for the rxn occuring if 0.10 moles AgNO3(s) is dissolved in the system treated in the above question. What effect does it have on pH? and Why?
