| Abstract: | In this paper, the reaction of potassium iodide and copper ion is studied, which formation is cuprous iodide. Redundant iodine and potassium iodide are gotten rid of when they are dried out. Coloured complex compound are formed by the reaction of trace amount of Nickel and dimethylglyoxime. It is measured by Spectrophotometry. Beer'law is obeyed in the range of 0-15 u g per 25 mL. Trace amount of Nickel in copper alloy is measured and its effect is satisfactory. |
