Answer 2

Given:

The oxidation potential of a metal is +0.80 V.

To find:

Will the metal displace hydrogen from acid ?

Solution:

First of all, the the oxidation potential of hydrogen is is considered to +1 V and as for the question the oxidation potential of the metal is +0.8 V.

Now, what is oxidation potential ?

• Oxidation potential gives us an idea of the tendency of the molecule to undergo oxidation by loss of electrons or electro-positive atoms.

• Higher oxidation potential means higher tendency to get oxidized.

• As per the data , hydrogen is having a higher oxidation potential as compared to the metal.

The reaction will be like :

$\boxed{ \bf M + AH \longrightarrow MA + H_{2}}$

• Here M is getting oxidised and H is getting reduced.

Since , hydrogen has a higher oxidation potential this reaction will not take place as it will have no tendency to get reduced.

So, hydrogen will not be displaced from the acid.
