Introduction:
The purpose of this experiment is to study a set of metals and their reactions reactions using different metals in an ordered activity series, the goal is to find the relative reactivity of them.Discovering why metals react with certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings, or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals, this is important. Manufacturing cars, or producing construction supplies all ties in with the activity series. Without it, cars or buildings could very well be rusting and dissolving around us.
