Hydrochloric acid (HCl) is a clear, strong inorganic acid commonly used in school science labs for experiments such as acid‐base reactions, pH testing, and metal reactivity demonstrations. For school use, it is supplied at low concentrations (0.1–1 M) to allow safe handling under teacher supervision. It is corrosive and can irritate or burn skin and eyes, so safety goggles, gloves, and lab coats must always be worn. Use only in a well‐ventilated area or fume hood and follow proper storage, handling, and disposal protocols. Never mix with incompatible chemicals unless instructed. Ideal for teaching chemical principles safely, it provides students with hands-on learning while adhering to laboratory safety standards
