- D. Ignoring spills
Answer
Wearing safety goggles
Explanation
Wearing safety goggles protects the eyes from potential splashes or spills of hazardous liquids during investigations.
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.
