Which statement about desiccators is NOT true?

• A. Keeps chemicals at high temperatures
• B. Protects hygroscopic or reactive with water
• C. Used to measure volumes
• D. Used to store volatile gases

Answer: (A)

Desiccators are designed to keep contents dry by creating a low-humidity environment with a desiccant inside a sealed chamber. They are not meant to heat substances or maintain high temperatures. Because their job is moisture control, they’re typically kept at room temperature and used to protect hygroscopic or water-reactive materials from moisture in the air. They won’t reliably or safely keep chemicals at high temperatures, which is why that statement is not true. The other points align with common uses: they help protect substances sensitive to water, and while they’re not measurement tools or storage for volatile gases, their primary purpose is to maintain dryness rather than measure volumes or contain gases.
