ELECTROCHEMICAL SERIES. Petr Vanýsek. There are three tables for this electrochemical series. Each table reliability. The values of reduction potentials. There are three tables for this electrochemical series. Each table lists standard reduction potentials, E° values, at K (25°C), and at a pressure of . Electrochemical Series of Metals (ESM). Different metals get ionised at different rates. For e.g., metals like sodium when exposed to air combine almost instantly.

There are a lot of songs and stories which can help you to memorize the electrochemical series faster. Here are some examples. Maybe some of them will help you to create your own song, story or ilustration to remember the series faster. On the video below is a really catchy song about the reactivity series: On the floor 0. Above the janitor live the bad guys, and below him live the good guys.

Maybe some of them will help you to create your own song, story or ilustration to remember the series faster. On the video below is a really catchy song about the reactivity series: On the floor 0.

Above the janitor live the bad guys, and below him live the good guys. The guy who lives on the top floor of the building, floor His name is Lithium a.

He constantly throws things out of the window and disturbs other neighbors. Neighbors who live below him have gone crazy, they can not stop him, so under his influence they started throwing things out of the window.

Electrochemical Series

In other words they oxidize. Neighbors who live under the janitor have apartments marked with positive numbers. When expressed in terms of the reduction potential, the change in value is as,.

By looking at the reaction, we can conclude that the oxidation half-reaction takes place at the Zn electrode. Hence it is acting as the anode.

For a redox reaction to be spontaneous or occur readily, the EMF of the cell must be positive. If it comes out to be negative, then the direct, spontaneous reaction cannot take place.

Galvanic Corrosion Risk

Such information is important in predicting the outcome or the stability of a metal salt solution when stored in another metal container. Given is: As seen from the reaction, the oxidation terminal will be the Nickel electrode.

As the EMF come out to be positive, it implies that copper sulfate will react when placed in a Ni vessel and hence cannot be stored in it. The metal undergoes oxidation, and the hydrogen ion by accepting the electron undergoes reduction. Lower is the reduction potential more negative , higher is the reactivity of the metal with the acid. Copper doesn't form its ions very readily, and its ions easily pick up electrons from somewhere to revert to metallic copper.

Copper II ions must be good oxidizing agents. Jim Clark Chemguide. Reducing agents and oxidizing agents A reducing agent reduces something else.

Summarizing this on the electrochemical series Metals at the top of the series are good at giving away electrons. They are good reducing agents.

The reducing ability of the metal increases as you go up the series. Metal ions at the bottom of the series are good at picking up electrons. They are good oxidizing agents. The oxidizing ability of the metal ions increases as you go down the series.
