-
Al and Mg
- Zn and Fe
- Zn and Pb
- Pb and H
- Au and Hg
The correct answer is: A
Explanation
The electrochemical series, also known as the activity series, is a list of metals listed in order of decreasing reactivity or in order of decreasing ease of oxidation.
Magnesium comes before Aluminium in the series
