Lesson 6: Redox reaction

Redox reaction

In the following reaction, let's think about what is being oxidized and what is being reduced.

\begin{aligned} \text H_2\text S(\text g)+\text{Br}_2(\text l)\rightarrow2\text{HBr}(\text l)+\text S(\text g) \end{aligned}

Choose the correct statements from the following.

(Choice A)
start text, B, r, end text, start subscript, 2, end subscript is reduced by gaining hydrogen.
(Choice B)
start text, B, r, end text, start subscript, 2, end subscript is oxidised by gaining hydrogen.
(Choice C)
start text, H, end text, start subscript, 2, end subscript, start text, S, end text is reduced by losing hydrogen.
(Choice D)
start text, H, end text, start subscript, 2, end subscript, start text, S, end text is oxidised by losing hydrogen.
