1. How would using 0.42 g CH3CO2Na * 3H2O instead of the amount called for in the procedure change the theoretical yield of Fe(C5H7O2)3 = 3.53g.
2. When a student sees crystals form after she added a few drops of water to the filtrate. Need chemical formula of the crystals.
3. Why the addition of water to the filtrate causes the crystals to precipitate from the solution.
4. Why is it more efficient to examine a small portion of the filtrate rather than the entire solution, when checking to see if crystalization is complete.
5. Why is it better to wash the collected crystals with distilled water instead of water--methanol mixture.
Please help on these questions. Have no clue at all.
