calculate the percentage of Mn and acetyl acetone and the empirical formula THEORY Manganese is a first row transition metal that has a tremendous variety of oxidation states that appear in its compounds. The oxidation numbers range from Mn (III) in compounds like Mn(NO)3CO to Mn (VII) in KMnO4. Compounds of manganese range in oxidation number between theses two extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful

small amount of lost product yields a great loss in the yield 4. These sources of error could be minimized by doing a larger reflux in order to increase the yield. However‚ as the purpose was to simply synthesis SnI4 in order to identify the stable oxidation states (the melting point range requires very little product) it would be advantageous to use the current method. This is due to the smaller quantity of materials needed for this type of reflux‚ thus making less of an environmental impact (using
