What is the reducing agent in the following reaction? cl2(aq) + 2br(aq) ——> 2cl-(aq) + br2(aq)

a. br2

b. cl2

c. br-

d. cl-

C) Br-

This is the reducing agent of the reaction.

Hope this helps!

Option (C) is the correct answer.

Explanation:

An element or substance whose oxidation state increases in a chemical reaction is known as reducing agent as the element itself gets oxidized.

On the other hand, an element or substance whose oxidation state decreases in a chemical reaction is known as an oxidizing agent as the element itself gets reduced.

For example,

Oxidation-half reaction : 2Br^{-}(aq) \rightarrow Br_{2} + 1e^{-}[/tex]

Reduction-half reaction :

Hence, we can conclude that in this reaction is the reducing agent.

b is the correct answer

mark me brainliest and hope this
