consider the following unbalanced redox reaction:

cr subscript 2 o subscript 7 superscript 2 minus, (aq) plus n o subscript 2 superscript minus, (aq) yeilds cr superscript 3 plus, (aq) plus n o subscript 3 superscript minus, (aq)

what is the reducing agent in the reaction?

The reducing agent in the given reaction is

Explanation:

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes oxidation reactions and oxidation reaction is defined as the reaction in which an atom looses its electrons.

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions and reduction reaction is the reaction in which an atom gains electrons.

For the given chemical reaction:

The half reactions for the above equation follows:

Oxidation half reaction:       ( × 3)

Reduction half reaction:      ( × 2)

In the above reaction, the reactant which is getting oxidized is . So, it is the reducing agent.

Hence, the reducing agent in the given reaction is

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
