alleryA reducing agent is a substance that:
ALoses electrons and is itself oxidised
BGains electrons and is itself reduced
CDonates protons
DAccepts protons
Answer & Solution
Correct answer: A. Loses electrons and is itself oxidised
1. A reducing agent gives away electrons to another species, reducing it.
2. In doing so, the reducing agent itself is oxidised.
3. (C) and (D) are Brønsted definitions for acids/bases, not redox.
