A reducing agent in a redox reaction is the substance that
Aloses oxygen and is itself reduced
Bneither gains nor loses oxygen
Cgains oxygen and is itself oxidised
Dalways forms a precipitate
Answer & Solution
Correct answer: C. gains oxygen and is itself oxidised
1. A reducing agent supplies electrons (or hydrogen) and removes oxygen from another substance.
2. In doing so it **gains oxygen and is itself oxidised**.
3. The oxidising agent is the opposite — it is reduced.
