Nitrates and potassium dichromate are considered as waste oxidizers.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Oxidizers are substances that can accept electrons in a reaction and often release oxygen, making fires more likely or more vigorous. Nitrates are classic inorganic oxidizers; they decompose or react to release oxygen that can feed combustion of fuels. Potassium dichromate is a strong oxidizing agent that readily oxidizes many substances and can release oxygen in reactions, especially under acidic conditions. Because these materials can intensify fires or react violently with reducing agents, wastes containing them are categorized as waste oxidizers and must be handled with proper segregation and storage to prevent hazardous interactions. So the statement is true.
