Which statement about bleach (sodium hypochlorite) is false?

• A. Bleach is a weak reducing agent.
• B. Nitrile gloves have a 480 min breakthrough time for bleach.
• C. If a significant amount of bleach is spilled on you, get into the safety shower.
• D. Bleach forms poisonous chlorine and chloramine gas when combined with ammonia.

Answer: (A)

Bleach acts as an oxidizing agent, not a reducing agent. The hypochlorite ion (ClO−) tends to accept electrons from other substances, oxidizing them and helping to break down stains and germs. Because of this oxidative power, saying bleach is a weak reducing agent is not correct. This oxidizing behavior also explains safety concerns: if bleach is spilled on skin, rinse with plenty of water and use a safety shower; mixing bleach with ammonia produces dangerous chlorine gas and chloramines, so keep them separate. Regarding protective gloves, nitrile gloves are commonly used, but breakthrough time depends on glove thickness, formulation, and bleach concentration, so a single fixed time isn’t universal—always check the supplier’s data for your specific conditions.
