Metal speciation in natural waters is of increasing interest and importance because toxicity, bioavailability, environmental mobility, biogeochemical behavior, and potential risk in general are strongly dependent on the chemical species of metals.etal speciation in natural waters is of increasing interest and importance because toxicity, bioavailability, environmental mobility, biogeochemical behavior, and potential risk in general are strongly dependent on the chemical species of metals.
Tomihahndorf, Public Domain. The activity series of metals is an empirical tool used to predict products in displacement reactions and reactivity of metals with water and acids in replacement reactions and ore extraction. It can be used to predict the products in similar reactions involving a different metal.The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom.For example, both magnesium and zinc can react with hydrogen ions to displace H 2 from a solution by the reactions: Mg(s) + 2 H + (aq) â H 2 (g) + Mg 2+ (aq).he activity series is a chart of metals listed in order of declining relative reactivity.
