2 Cu ₂ O (s)+ Cu ₂ ~S (s) 6 Cu (s)+ SO ₂(g) the oxidant and reductant respectively in the above reaction are
Options
- Aoxide of Cu ₂ O and sulphide of Cu ₂ ~S
- Bsulphide of Cu ₂ ~S and oxide of Cu ₂ O
- CCu ( I ) of Cu ₂ O , Cu ₂ ~S and sulphide of Cu ₂ ~S
- DCu ( I ) of Cu ₂ ~S , Cu ( I ) of Cu ₂ O
Correct answer
C. Cu ( I ) of Cu ₂ O , Cu ₂ ~S and sulphide of Cu ₂ ~S
Step-by-step solution
Cu ( I ) of Cu ₂ O (s) and Cu ₂ ~S (s) undergoes reduction to form Cu (s) while sulphide of Cu ₂ ~S undergoes oxidation to form SO ₂( ~g ) . Thus, Cu ( I ) of Cu ₂ O Cu ₂ ~S acts as an oxidising agent (oxidant) and sulphide of Cu ₂ Sacts as a reducing agent (reductant).
