Block, George M. McKelvy. There were a few deviations from the procedures: 1. Instead of measuring 10 to 15 mL of standard .1 M sodium oxalate solution, we were told to use just 5 mL. 2. Instead of weighing .3 g of the cobalt oxalate hydrate, we were told to use only .2 g. Data: see attached excel sheet. Results: see attached excel sheet Sample Calculations: see attached sheet Discussion: Conclusion: The empirical formula of our cobalt oxalate hydrate sample is Co 3 (C 2 O 4 ) 2 * H 2 O....
