Question
What safety precautions should be taken when using liquids in experiments involving chemical cells?
Answer
When using liquids in experiments with chemical cells, it is important to wear safety goggles and gloves to protect against spills and splashes. Additionally, work in a well-ventilated area and ensure that all liquids are handled carefully to avoid accidents.
Explanation
This question tests the student's understanding of safety protocols in a laboratory setting, specifically related to the handling of liquids in chemical experiments. It emphasizes the importance of personal protective equipment and safe working conditions.
Common mistake
Mixing up safe handling of acids and bases
Students often think that all liquids used in simple cells are harmless and can be handled without precautions, or they treat acidic and basic electrolytes the same way, ignoring the risk of splashes and corrosion.
Remind students that electrolytes can be acidic, basic or neutral, and that acidic or basic solutions can be corrosive or cause skin irritation. They should wear appropriate PPE (gloves, goggles, lab coat), use a fume hood or well‑ventilated area, and handle all liquids carefully to avoid splashes or spills. Emphasise that safety procedures are required for all liquids, not just for the cell’s operation.
