If a basic substance is highly soluble in water and can burn skin, how should it be used in the laboratory?

Answer and explanation

Correct answer: With safety equipment and care

The governing concept is laboratory safety when handling a soluble, corrosive base. A strong base can damage skin and eyes, and dissolving some bases in water releases heat; therefore direct contact and careless mixing are unsafe. The substance should be handled with gloves, eye protection, suitable tools, clear labelling, and controlled procedures. Option B is correct. Eating it or storing it without a label creates additional hazards, while bare-hand use ignores its caustic nature.
