ACTIVITY SERIES The activity series of metals is an list of metals ranked in order of decreasing reactivity to displace hydrogen gas from water and acid solutions. It can also be used to predict which metals will displace other metals in aqueous solutions. In introductory chemistry‚ the reactivity series or activity series is an empirical series of metals‚ in order of "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water‚ single
