Question

In a redox reaction, which particles are lost and gained in equal numbers?(1) electrons (3) hydroxide ions

(2) neutrons (4) hydronium ions

Answer 1

In redox reactions the particles that are lost and gained are ELECTRONS. (option 1)

Answer 2

Answer: Option (1) is the correct answer.

Step-by-step explanation:

A redox reaction is a reaction in which both oxidation and reduction takes place.

For example,
`H_(2) + F_(2) \rightarrow 2HF`

Oxidation-half reaction :
`H_(2) \rightarrow 2H^(+) + 2e^(-)`

Reduction-half reaction :
`F_(2) + 2e^(-) \rightarrow 2F^(-)`

Hence, we can see that electrons are involved in a redox reaction.

Therefore, we can conclude that in a redox reaction, electrons are the particles which are lost and gained in equal numbers.
