• The?E^??values of a species indicate how?easily?they can get?oxidised?or?reduced
• In other words, they indicate the relative?reactivity?of elements, compounds and ions as?oxidising agents?or?reducing agents
• The?electrochemical series?is a list of various?redox equilibria?in order of decreasing?E^??values
• More positive?(less negative)?E^??values indicate that:
  • The species is easily?reduced
  • The species is a better?oxidising agent
• Less positive?(more negative)?E^??values indicate that:
  • The species is easily?oxidised
  • The species is a better?reducing agent

Example of an electrochemical series in which the equilibria are arranged in order of? decreasing E^??values
