Instructions: Watch the videos below for the various reaction of acids and bases with other substances. You may recall some of the observations made during your practical lessons. Make relevant observations and write suitable equations to represent the reaction. Write your answers in the link provided here.
A summary of basic knowledge of Acids, Bases and Indicators are included here.
1. Acids + Reactive Metals (Group I, II or III, Zinc or Iron etc) --> salt + hydrogen gas
E.g. Reactions of various metals with hydrochloric acid
2. Acids + Metal Carbonates --> salt + water + carbon dioxide gas
E.g. Calcium carbonate with acid
3. Acids + Base --> Salt + water (a form of neutralisation reaction)
E.g. Titration of hydrochloric acid with sodium hydroxide
4. Alkalis + Ammonium salts --> salt + ammonia gas + water
E.g. ammonium chloride + sodium hydroxide --> sodium chloride + ammonia gas + water
