Our final solution is containing ethanol or not. A simple chemical experiment is used here for this purpose. Here we have used two types of solution. They are (i) 1M Na0H (Sodium Hydroxide) solution &(ii) 0.5 M Iodine Solution.20 drops of solution was taken in a test tube using pipette. Then 50 drops of iodine solution was added in that solution. After those 20 drops of Sodium Hydroxide solution is added. After 2 minutes the solution is observed carefully. The solution in the test-tube was being cloudy and then a yellow precipitate of triidomethane (iodoform) had seen.
