As per standard reduction potential values, which is the strongest reducing agent among the given elements?
- A Rb
- B Sr
- C Na
- D Mg
Answer & Solution
Correct Answer
(A) Rb
Step-by-step Solution
Detailed explanation
The tendency of an element to lose an electron is measured by its oxidation potential more the value of \(\mathrm{E}^{\circ}\) of an element stronger will be its reducing character. The alkali metals have a low value of ionization energy which decreases down the group and so can…
