Potassium dichromate acts as a strong:
Correct answer: A. Oxidizing agent
- A. Oxidizing agent
- B. Reducing agent
- C. Bleaching agent
- D. Dehydrating agent
Explanation
Potassium dichromate (K2Cr2O7) is a strong oxidizing agent. It readily accepts electrons from other substances, causing them to be oxidized in a chemical reaction. This property makes potassium dichromate useful in various chemical processes, such as in the preparation of aldehydes from primary alcohols. Therefore, option a is correct.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
