Metals and acid4 steps · you test each metal

Test each metal. Tap a tube to drop the metal into the acid. Watch how fast it fizzes.
Put them in order. The more vigorous the reaction with acid, the more reactive the metal. Copper did not react at all. It is the least reactive of the five.
Name the products. A reactive metal and an acid make a salt and hydrogen. Hydrochloric acid makes chlorides.
Test the gas. Hold a lit splint at the mouth of the tube. Hydrogen burns with a squeaky pop.
