At Miramar, we studied single-displacement reactions. For example, when you put a piece of iron metal in copper (II) sulfate solution, the copper comes out of the solution and plates out as copper metal on the iron. Some of the iron dissolves into the solution too. Because iron favors being dissolved in the solution more than copper does, we call the iron a more "active" metal than copper.
