Question

The metals with the highest and the lowest standard reduction potentials (SRP) values are:

• A. silver and lithium
• B. fluorine and lithium
• C. fluorine and silver
• D. silver and potassium

Answer 1

The correct option is A silver and lithium

Fluorine is one of the best oxidizing agents and has the highest reduction potential value (+2.87V) Since Fluorine is nonmetal.

Lithium belongs to the alkali metals and has the lowest ionization enthalpy.

It has a strong tendency for removal of valence shell electron and lowest tendency to accept electrons and prefer to undergo oxidation the metal having the lowest tendency to accept electrons have the lowest standard reduction potential.

Thus, Lithium has the lowest standard reduction potential

Hence, the correct option is $\text{A}$
