electrochemical series

Postby Kaylee Clarke 1G » Fri Mar 13, 2020 6:23 pm

in the outline, it mentions an electrochemical series. what is that referring to?

The electrochemical series is a table of the relative strengths of oxidizing and reducing agents. It shows the oxidizing and reducing power of redox couples, with the strongest oxidizing agents on the top left and strongest reducing agents at the bottom right.

Knowing oxidizing and reducing power helps determine whether K is less or greater than 1, which allows you to determine which direction is favored for an electrochemical cell, or in other words, if the forward or reverse reaction is spontaneous.

It also helps indicate whether cell potential will be positive or negative, given the anode and cathode are defined.
I have attached a picture of the electrochemical series chart.

The more positive the electrode, the more oxidizing the reactant. By looking at the electrochemical series, you can determine which reactants would be better oxidizing or reducing agents.

The electrochemical series is just a list of experimentally obtained reaction cell potentials. The more positive the value, the more likely the molecule will be reduced.

Will knowing the electrochemical series and the chart be important or will any necessary information be provided by the problem?
