O-Level Pure Chemistry: Acids, Bases & Salts: Common Pitfalls

Acids and bases

Acid reacts with base → salt + water. Strong vs weak acids: complete vs partial ionisation.

Salts

Made by neutralisation (acid + base/alkali/carbonate). Solubility rules help predict ppt formation.

Exam habits

  • Write word and balanced chemical equations.
  • State observations (effervescence, colour change).
  • Memorise key solubility rules: all nitrates soluble, most chlorides soluble (except Ag, Pb).
