Question

Identify the reactant that is reduced in the following reaction: f₂ (g) + 2NaBr (aq) → 2naf (aq) + br₂ (l)?

1) f₂ (g)
2) 2NaBr (aq)
3) 2naf (aq)
4) br₂ (l)

Answer 1

F₂ (g) is the reactant that is reduced in the given reaction, as it gains electrons to form F⁻ ions in the formation of NaF.

Step-by-step explanation:

The reactant that is reduced in the reaction F2 (g) + 2NaBr (aq) → 2NaF (aq) + Br2 (l) is F₂ (g) . In a redox reaction, reduction refers to the gain of electrons. Fluorine in F2 gains electrons to form fluoride ions, F−, in NaF. Therefore, F2 is being reduced, making it the correct answer.

As for the rest of the options: 2NaBr (aq) is the reactant that is being oxidized as it loses electrons to form Br2. The product of the reduction, 2NaF (aq), is not being reduced itself, and Br2 (l) is the product of the oxidation.
