REDOX EQUILIBRIA SL - chemistryatdulwich
... reduced. Therefore the reactivity of a metal or non-metal is about how easily it is oxidized or reduced or how strong a reducing or oxidizing agent it is. The strength of an oxidising or reducing agent can be found by using it in displacement reactions with other oxidising or reducing agents e.g. li ...
