What is the meaning of the Electromotive Series Table? How do you predict reactions using this table?
Understand the Problem
The question is asking for a definition of the electromotive series table and how to use it to predict chemical reactions. This involves understanding the arrangement of elements in the table and how their relative positions indicate their reactivity and ability to displace other elements in a reaction.
Answer
The electromotive series table ranks metals by reactivity, predicting displacement reactions. Metals higher in the series displace those lower in the series.
The electromotive series table (also known as the electrochemical or activity series) lists metals in order of their standard electrode potentials, indicating their relative reactivity. It helps predict whether a metal will displace another from its compound in a redox reaction. A metal higher in the series (with a higher reduction potential) will displace a metal lower in the series.

More Information
The series is crucial in understanding corrosion and battery design, as it helps determine which metals will corrode preferentially and the potential voltage of electrochemical cells.
Tips
A common mistake is to confuse the direction of reactivity. Remember, a metal higher in the series is more likely to be reduced and will displace a metal lower in the series from its salt solution.
