1. You dissolve 5.00 g sodium hydrogen oxalate (NaHC2O4 ) insuffircient water to produce a final solution volume of 100.0 mL.Assuming all of the solid dissolves, calculate the pH of thissolution.
2. You dissolve 5.00 g of sodium oxalate (Na2C2O4) in sufficientwater to produce a final solution volume of 100.0 mL. Assuming allof the solid dissolves, calculate the solution pH of thissolution.
3. You dissolve 5.00 g of sodium hydrogen oxalate and 5.00 gsodium oxalate in sufficient water to produce a final solutionvolume of 250.0 mL. Assuming both solids dissolve completely,calculate the pH of this solution.
4. Calculate the pH of the solution prepared in question #3after 2.00 mL 1.00 M sodium hydroxide is added to it.
5. You dissolve 5.00 g sodium hydrogen oxalate and 1.00 g sodiumhydroxide in sufficient water to produce a final solution volume of250.0 mL. Assuming both solids dissolve completely, calculate thepH of this solution.
6. Calculate the pH of the solution prepared in question #5after 2.00 mL 1.00 M hydrochloric acid is added to it.
