What is a reduction potential chart show? What information does it have?

It shows how likely chemical species are to gain electrons and therefore, be "reduced". Reduction potential is measured in volts(V) and the more positive the reduction potential value, the more likely it will be reduced.

Answer:

It shows the reduction-oxidation tendency of chemical species present in the chart.

Explanation:

The reduction potential chart also known as activity series or electrochemical series is a reference series or chart constructed on the basis of reduction potential of standard hydrogen electrode (SHE). The standard reduction potential of SHE is considered to be zero.

Any species which can reduce SHE has negative reduction potential in the chart.

Any species which can oxidize SHE has positive reduction potential in the chart.

Higher the reduction potential more the tendency to undergo reduction and to oxidize others.

Lower the reduction potential more the tendency to undergo oxidation and to reduce others.
