S3 Chemistry: Hydrogen Chloride Gas and Hydrochloric Acid

These teacher-prepared chemistry notes by Ssegujja Benard cover hydrogen chloride gas, hydrochloric acid and chloride salts. They outline laboratory preparation, physical and chemical properties, identification tests and uses of hydrochloric acid. Reaction equations illustrate reactions with metals, carbonates, alkalis and other substances. The material also discusses testing for soluble chlorides, chloride solubility, behaviour on heating and absorption of atmospheric moisture. Embedded exercises ask learners to explain preparation procedures, apparatus choices and differences between hydrogen chloride in aqueous and organic solvents.
