Hydrogen peroxide, $\text{H}_2\text{O}_2$, breaks down to produce water and oxygen. Bromide ions catalyse the reaction. first step $2\text{Br}^-(aq) + \text{H}_2\text{O}_2(aq) + 2\text{H}^+(aq) \rightarrow 2\text{H}_2\text{O}(l) + \text{Br}_2(aq)$ second step $\text{H}_2\text{O}_2(aq) + \text{Br}_2(aq) \rightarrow 2\text{Br}^-(aq) + 2\text{H}^+(aq) + \text{O}_2(g)$ Which row is the correct one?
- Aheterogeneous; bromide ions are oxidised
- Bheterogeneous; bromide ions are reduced
- Chomogeneous; bromide ions are oxidised
- Dhomogeneous; bromide ions are reduced
