Assertion (A): While the extraction of copper, one of the steps involved is Cu 2 S + 2Cu 2 O → 6Cu + SO 2
Reason (R) : In this reaction Cu 2 S is the reducing agent whereas Cu 2 O is the oxidising agent.
An oxidising agent is the compound that gets reduced.
- gains electrons
- gains hydrogen
- or loses oxygen
A reducing agent is a compound that gets oxidised .
- loses electrons
- loses hydrogen
- or gains oxygen.
In the given equation,
Cu 2 S + 2Cu 2 O → 6Cu + SO 2
Sulphur gets oxidised by gaining oxygen, while Cu loses oxygen.
Hence, Sulphur is the reducing agents and copper is the oxidising agent.
- The Assertion is True.
- Reason is also False.
So, the correct answer is (c)
