How to Understand how metals react in hydrochloric acid

In this video tutorial the instructor talks about Hydrochloric acid (HCL) and how it reacts to a few metals. To try this out take 30 ml of concentrated hydrochloric acid in a beaker. You need to employ caution while handling acids, especially if you use strong ones. Now you can throw small pieces of different metals into it carefully to see how it reacts with different metals. For instance when this HCL comes in contact with metals various reaction take place depending up on the metal. Like if aluminum is thrown into it at first the acid reacts with the oxide layer on the surface of the piece and Aluminum chlorate is produced. Depending up on the metal there can be lots of kinds of reactions. This video shows how HCL reacts with the metals Aluminum, Zinc, Copper, Vanadium, Cadmium and a few others. This video demonstrates the reaction of HCL with different metals.
