Reactivity series mnemonic11/16/2023 Therefore, leading to a higher reactivity.The higher a metal’s oxidizing potential, the faster it may lose electrons.Hence, the rule “the metal that produces the cation can only displace cation, as well as the metal that creates the anion can displace any anion” applies.All in all, the metals displacing processes are cation displacement reactions.Therefore, implying that it is a more efficient reducing agent.Ĭomparing the relative energies of metals in displacement processes basis their placement in the activity series!.However, a negative value indicates that the electrode’s reduction potential is weaker.Hence, it works as a more powerful oxidizing agent.A positive value implies that the electrode has a higher reduction potential.However, when it is negative, the reaction of the cell is not feasible, leading to an inaccurate cell representation.Ĭomparison of the reactivity of different metalsĪs a matter of fact, the oxidation or reduction of various substances and ions are known through the electrochemical series.Įxamining a molecular model in physical chemistry Benefits of the electrochemical series Comparison of various metals’ respective oxidizing and reducing powers.As a matter of fact, a feasible reaction represents the cell effectively.All in all, if the EMF of the substance’s cell is positive, the reaction is feasible.However, it is possible only if the substances with greater potential reduce, while those with lesser potential lose their electrons or oxidize.Basis the values of E of the two different electrodes, the electrochemical series can predict the feasibility of the provided redox reaction.Predicting the feasibility of the redox reaction Therefore, substances having -E values have the potential to free the Hydrogen from different acids.Hence, when such a substance is placed in an acid solution, it gets oxidized, and an effective reduction of H+ ions occurs to form hydrogen gas.
