Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
C
Explanation
An oxidizing agent is a substance that tends to accept electrons and undergo reduction in a chemical reaction. Among the ions mentioned:
1. Au³+ - Gold(III) ion typically acts as a reducing agent, not an oxidizing agent.
2. Fe³+ - Iron(III) ion can act as an oxidizing agent in certain reactions, accepting electrons and undergoing reduction.
3. ClO- - Hypochlorite ion can act as an oxidizing agent, as it has the potential to accept electrons.
4. Ca²+ - Calcium ion is not typically an oxidizing agent. It tends to lose electrons and undergo oxidation.
Therefore, the ion that can be used as an oxidizing agent from the options provided is ClO- (hypochlorite ion).
