Detailed Solution
Download Solution PDFThe correct answer is HAsO2 (aq)
Key Points
The balanced chemical equation for the given reaction is:
HAsO2(aq) + 2Sn2+(aq) + 4H+(aq) → As(s) + 2Sn4+(aq) + 2H2O(l)
In this reaction, HAsO2 (aq) acts as an oxidizing agent and Sn2+ acts as a reducing agent.
Important PointsOxidizing agent:
- An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction.
- Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reduced.
- Chlorine is used as the oxidizing agent for the purification of water.
Reducing agent:
- A reducing agent, or reductant, loses electrons and is oxidized in a chemical reaction.
- Examples of reducing agents include the earth metals, formic acid, and sulfite compounds
