Unformatted text preview: The activity series is a list of metals and their half-reactions arranged in order of decreasing ease of oxidation or increasing ability to take an electron. How do you use this series? Very simply, any substance on the right-hand side of the arrows will be strong enough to take an electron from any substance above it on the left-hand side of the arrows. For example, if a Ag + cation gets close to an Fe atom then the Ag + cation will take an electron away from the Fe atom. In terms of a chemical reaction the activity series predicts 2Ag + + Fe → 2 Ag + Fe 2+ In contrast, when a Fe 2+ cation meets a Ag atom, the Fe 2+ cation will not be strong enough to take electrons away from the Ag atom. That is, 2 Ag + Fe 2+ — X → 2Ag + + Fe What happens when we mix Ca metal and HCl acid?...
