Question

Chromium seem to be less reactive than estimated from its standard reduction potential value because of formation of oxide layer.

If true enter 1, else enter 0.

Answer 1

The reactivity series of chromium seems the strict reverse order of standard electrode potentials.

It is also effect for the oxidation state of Chromium.

Cations of the second and third row transition metals in lower oxidation states (+2 and +3) are much more easily oxidized than the corresponding ions of the first row transition metals.

For example, the most stable compounds of chromium are those of Cr(III), but the corresponding Mo(III) and W(III) compounds are highly reactive.

So, the correct option is 1.
