I synthesised potassium Trioxalato Ferrate III . It's having this beautiful limegreen color to it. The points to note is that we should not keep it
open in air as it decomposes.
I will give down the procedure I used to create it
1) Prepare a solution of 3.0 g of oxalic acid in 12.5mL of hotwater contained in a clean 50 mL beaker.
2) To the above solution, add 3.8 g of potassium hydroxidegradually in lots, with stirring so that it dissolves completely.
3)Add 2.5 g of ferric chloride into the above solution withconstant stirring till it is completely dissolved.
4)Filter the solution and concentrate the green filtrate byheating in a porcelain dish over a water bath and cool themixture slowly.
5)Filter the crystals so formed, wash with 1:1 mixture of coldwater and alcohol and dry them by pressing between thefolds of a filter paper.
I will also post down a link to the video where I synthesised it using the above procedure
