S3 Chemistry: Hydrogen Chloride and Hydrochloric Acid

These teacher-prepared notes by Ssegujja Benard of Trinity College Nabbingo cover hydrogen chloride gas, hydrochloric acid and chloride salts. They outline laboratory preparation, physical and chemical properties, reactions with metals, carbonates and bases, and industrial uses of hydrochloric acid. Further sections explain chloride identification using silver nitrate and ammonia, solubility, and behaviour on heating. Exercises ask learners to describe experimental procedures, write equations and explain differences between aqueous and non-aqueous hydrogen chloride solutions. Some chemical statements and equation notation require correction.
