Quick revision
Revisit the essentials, then return to an explanation when you need it.
Acids supply H+; alkalis supply OH-. Acid + base gives salt and water; carbonate also gives CO2; suitable metal gives H2. Alkali and ammonium salt release NH3 on warming.
Pure only
Pure: select salt preparation from solubility, separate acid strength from concentration, and interpret Haber conditions using supplied yield/rate/cost evidence.
