Experimental

Common household product aluminum (Al) foil contains property that reactions when mixed with Copper Chloride (CuCl2) and water (H2O) creates a chemical reaction visible to eye. Upon starting you can first indict it’s a chemical change with color change, changing from a bright teal blue. Then temperature change as the glass fogs and you can feel the glass get slightly warm and bubble, this being an exothermic process. Then the aluminum foil began its own reaction, changing colors from a once shiny metallic silver, to a reddish brown color. The aluminum foil had reacted with the copper chloride and turned into copper itself. This experiment is a indicative example of chemical reactions noticeable to eye in chemistry. Color change, temperature change, the making of gases, etc.
