WebThe third class contains metals such as chromium, iron, tin, and lead, which react only with strong acids. It also contains even less active metals such as copper, which only dissolves when treated with acids that can oxidize the … WebThe reactivity of metals The reactivity series lists metals from the most reactive to the least reactive. A metal can displace a less reactive metal from its compounds. This is useful...
