An experiment to find the empirical formula when copper reacts with iodine Introduction: This experiment has been carried out to find out the empirical formula of the following reaction. Copper + Iodine › Copper Iodide It is important to find out the mass of the copper and iodine both before and after the experiment, so that the empirical formula can be calculated. Method: A length of copper strip was cleaned using emery paper, then wiped with dry filter paper. After, the copper strip was weighed. Approximately 0.3g of iodine crystals was weighed and then placed in to a dry boiling tube. The copper strip was then placed into the boiling tube, two centimetres above the iodine, and bent over the edge to place it in a secure position. The boiling tube was then heated over a Bunsen (tongs were used to hold the boiling tube). Soon, vapour could be seen. At the moment the vapour was seen,...
