Question

In the redox reaction AgNO3+Na→NaNO3+Ag, which element has been reduced?

Answer 1

Silver ( Ag ) has been reduced from +1 state to 0

Answer 2

In the given chemical equation, the element that has been reduced is silver.

Explanation:

Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

For the given chemical equation:

$AgNO_3+Na\rightarrow NaNO_3+Ag$

The half reactions for the given equation follows:

Oxidation half reaction:  $Na\rightarrow Na^++e^-$

Reduction half reaction:  $Ag^++e^-\rightarrow Ag$

As, silver is gaining 1 electron, it is getting reduced.
