Question

In the reaction of sodium with bromine, explain which atom is reduced.

I need you to show ALL the steps because I don't understand.

Answer 1

The reduced atom is Br.

Step-by-step explanation:

• The oxidation-reduction reaction contains a reductant and an oxidant (oxidizing agent).

• The oxidation process is the process in which electrons are lost and produce positively charged ions.

• The reduction process is the process in which electrons is gained and negatively charge ions are produced.

• In the reaction of chlorine with calcium:

2Na + Br₂ → 2NaBr,

Na loses 1 electrons and is oxidized to Na⁺. (Na → Na⁺ + e).

Br₂ gains 2 electrons and is reduced to 2Br⁻. (Br₂ + 2e → 2Br⁻).

So, the reduced atom is Br.
