Tin iodide (SnI 2) with a purity of 99.99% was further purified in a tube furnace based on the different boiling points of tin(ii) iodide and tin(iv) iodide. > In Preparation Copper(I) iodide can be prepared by heating iodine and copper in concentrated hydriodic acid, HI.In the laboratory however, copper(I) iodide is prepared by simply mixing an aqueous solution of potassium iodide and a soluble copper(II) salt such copper sulfate. Weigh 1g of mossy Sn and 2n4g of I2 in a 25 mL E. flask along with a stir bar. The first stage is the same as the method for making copper(II) sulphate ( shown above ). A stoichiometric ratio of tin(II) iodide (Kojundo Chemical Laboratory Co., Ltd) and indium(I) iodide (Aldrich) was added to one side of an H-shaped glass tube. Preparation and Composition of Tin (IV) Iodide Procedure:- > 3.0020g of Tin (II) Chloride (SnCl2.2H2O) was mixed with 25 cm3 of an equivolume mixture of glacial acetic acid and acetic anhydride in a 100 ml "Quickfit" flask. Preparation It is normally made by reacting iodine with tin. The analysis of the compound to determine the oxidation state of tin in the compound. Tin has two oxidation states (II and IV), and exhibits approximately equal stability in both its II and IV oxidation state. Preparation It is made by dissolving tin or its oxide in hydriodic acid. Potassium is already in its most stable oxidation state (+I), so tin will be reduced, from $\ce{Sn}$(IV) to $\ce{Sn}$(II). Tetra-Iodide Roscoe G.
