5.6g of Ferric chloride hexahydrate and 6.7g of ferrous sulphate were dissolved in 50ml of 0.5M HCl. 90 ml of 1.5M Sodium Hydroxide was added dropwise to the solution which is under vigorous mixing on a hot plate stirrer set at 80 degree Celsius at 100rpm. the pH of the solution was observed to be highly basic (pH 12), on obtaining a viscous and jet-black colouration, transfer the solution to 50 ml centrifuge tubes. Around 83mL
