of the potassium oxalate has dissolved. 3. While the potassium oxalate solution is heating, you can make your solution of iron (III) chloride hexahydrate (FeCl3·6H2O). In a second 100 mL beaker, weigh out approximately 2.5 g of iron(III) chloride hexahydrate. Record the exact mass using all the digits available on the balance. 4.

Potassium Ferric Oxalate crystals is a light green colour complex compound prepared from ferric sulfate and barium oxalate in the presence of oxalic acid. This preparation of potassium ferric oxalate is an example of an Oxidation-Reduction reaction.
When the reaction has subsided (about 15 minutes), dissolve 2.10 g (2.1085 g) of potassium oxalate monohydrate, K.C.04.H0, in the hot green-black liquid and heat to boiling for 5 minutes. Cool the viscous reaction to room temperature and add 10 mL of 95 % ethanol and cool the beaker further in …
Aluminium metal was reacted with potassium hydroxide to produce the [Al(OH) 4] - ion. Next, oxalic acid (H 2 C 2 O 4) is added, which neutralizes the excess hydroxide and provides a source of the oxalate ion. Lastly, the [Al(C 2 O 4)] 3-ion that is produced is precipitated as the potassium salt by the addition of ethanol. The grey solution was turning to colourless solution.
A. Preparation of K 3 [Fe(C 2 O 4) 3].3H 2 O 1. Weigh approximately 9.0 g of hydrated potassium oxalate, K 2 C 2 O 4.H 2 O into a 250 mL beaker. 2. Add 30 mL of distilled water and heat to dissolve (do not boil). 3. In a second small beaker dissolve 4.4 g of FeCl 3.6H 2 O in a minimum amount of cold water (10-15 mL). Add the FeCl 3.6H 2 O ...
