Question

When the electrodes (metals and non-metals) in contact with their ions are arranged on the basis of the values of their standard reduction potentials or standard oxidation potentials, the resulting series is called:

• A. electrochemical series
• B. electromotive series
• C. reduction series
• D. none of the above

Answer 1

The correct option is B electromotive series

By measuring the potentials of various electrodes versus stand ard hydrogen electrode (SHE), a series of standard electrode potentials has been established.
When the electrodes (metals and non-metals) in contact with their ions are arranged on the basis of the values of their standard reduction potentials or standard oxidation potentials, the resulting series is called the electrochemical or electromotive or activity series of the elements.
