Question

What reaction is depicted by the given equation: Au3+ + 3e− Au

Answer 1

Reduction reaction is in progress
bcz gain of electron 3e- to Au atom

Answer 2

Answer: It is a type of reduction reaction.

Explanation: Reduction reactions are a type of reactions in which oxidation number is reduced by the result of gain in electrons.

For a given reaction:

$Au^{3+}(aq.)+3e^-\rightarrow Au(s)$

The oxidation state of Au on the reactant side is +3 and is getting reduced to 0 by the gain of 3 electrons. Hence, this reaction is considered as a reduction reaction.
