Question

Mg has favourable standard reduction electrode
potential (EO
0
=-2.37V) but it does not react
Mg2+ /Mg
readily. It is because of
1) its resemblance to Li
2) fromation of protective oxide layer
3) its oxidising nature
4) its reaction with acids​

Answer 1

Mg has favourable standard reduction electrode

potential (EO0=-2.37V) but it does not react

Mg2+ /Mg readily. It is because of 1) its resemblance to Li.

Explanation for the answer:

• The reduction potential of a species refers to its tendency to gain electrons and get reduced.
• It is measured or calculated in millivolts or volts.
• Larger positive values of reduction potential are generally indicative of a greater tendency to get reduced.
• Hence, the correct answer among all the options is option 1) its resemblance to Li.
