Micaela A. JaramilloCHEM 121Section 2October10, 2016Partner: Morelia CuervasSynthesis of Potassium Ferric Oxalate TrihydrateIntroductionIn this lab we will synthesize Potassium Ferric Oxalate Trihydrate which will crystalize the solution froman aqueous solution. From this we will be able to determine the formula for the product.Experimental DataMass of Ferrous Ammonium Sulfate Hexahydrate: 5.0228g (Light blue, small granules)H2SO4- 5 drops (Clear liquid)1M H2C2O4- 25mL (Clear liquid)1M H2C2O4- 8mL to boiling solution; combined with Ferrous Ammonium Sulfate Hexahydrate - yellow,as it heat up it becomes a more solid color, looks like orange juice. As it settles the liquid isbecoming clearer and the solid is a solid color.Distilled Water - 20mL (clear liquid)K2C2O4-10mL (Clear liquid, solid at the bottom of the bottle)H2O2-After K2C2O4is added to the mixture it turned orange.After hydrogen peroxide is added the solution turns a dark red/brown.After Oxalic Acid is added the solution turned green.When Ethyl Alcohol was added the solution turned a creamy green color and began crystalizing.Addendum DataMass of Cupric Sulfate: .5051g (Electric blue granules)As it was heated up it turned into a white powder and once water was added it turned back toblue.Mass of Magnesium Sulfate Heptahydrate: .5031g (White granules)As it was heated up it turned into a white powder, after water was added it was rehydrated.Data AnalysisTheoretical Yield of Potassium Ferric Oxalate Trihydrate:6.2916gActual Yield of Potassium Ferric Oxalate:4.4067gPercentage Yieldof Potassium Ferric Oxalate Trihydrate:70.4%(4.4067g)/(6.2916)*100%
