Which of the following statements is incorrect about bleaching powder?
Correct answer: D. It acts as a reducing agent
- A. It is mixed salt
- B. It has 35- 40 % available chlorine
- C. It acts as an oxidizing agent
- D. It acts as a reducing agent
Explanation
Bleaching powder (calcium hypochlorite, Ca(ClO)2) is a compound commonly used for bleaching, disinfection, and water treatment. It is a mixed salt containing calcium cations (Ca2+) and hypochlorite anions (ClO-). Bleaching powder is primarily known for its oxidizing properties, not reducing properties. It acts as an oxidizing agent, meaning it readily donates oxygen or accepts electrons from other substances during a chemical reaction. In bleaching processes, it oxidizes colored substances, making them colorless.
