Question
$2\text{Cu}_2\text{S}+3\text{O}_2\xrightarrow{ \ \ \ \ \ \ \ \ }2\text{Cu}_2\text{O}+2\text{SO}_2$ In this reaction which substance is getting oxidised and which substance is getting reduced. Name reducing agent and oxidising agent.
✓

Answer

$\mathrm{Cu}_2 \mathrm{S}$ is getting oxidised, whereas $\mathrm{O}_2$, is getting reduced. $\mathrm{Cu}_2 \mathrm{S}$ is reducing agent, whereas $\mathrm{O}_2$ is oxidising agent.
