Four alkali metals

A,B,C

and

D

are having respectively standard electrode potential as

- 3.05, - 1.66, - 0.40{\kern 1pt} {\kern 1pt} \mathrm{and}{\kern 1pt} {\kern 1pt} 0.80

. Which one will be the most reactive?

View answer and explanation

Correct option: A

A

Option A is correct because the most reactive alkali metal is the one with the most negative standard electrode potential. A more negative value indicates a greater tendency to lose electrons and undergo oxidation. Among the given options, A has the most negative value (-3.05), making it the most reactive.
