Question

Strongest reducing agent among K Mg At Cr

Answer 1

Answer:

For the given elements, value of reduction potential will be as follows. Na = -2.71 V, Mg = -2.38 V, Al = -1.66 V, and K = -2.92 V. Larger is the value of electrode potential stronger will be reducing power of an element. Hence, we can conclude that out of the given options K is the strongest reducing agent.

Answer 2

Lithium metal is therefore the strongest reductant (most easily oxidized) of the alkali metals in aqueous solution. The standard reduction potentials can be interpreted as a ranking of substances according to their oxidizing and reducing power.
