Procedure

Two grams of chromium plus 6 oxide (0.02 mol) is reacted with 0.03 moles of sulphuric acid in the presence of 0.04 moles of ethyl alcohol. The chromium plus 6 oxide is reduced to chromium plus 3 sulphate. The reaction mixture is heated and boiled until the solution turns green and no odor of acctaldehyde is given off. Thereafter 2.98 grams of L methionine is added and the mixture is heated on a steam bath until a dark green colored paste forms. The mixture is dried in a hot air oven and instrumental, and quantitative analysis as pre-viously described reveals the presence of a 1:1 L-form complex chromium methionine sulphate salt.
