Step-by-step lessons on Edexcel IGCSE Chemistry Acids, bases and salt preparations. Each one builds up to exam-style questions. Build a solid grasp of atomic structure, bonding and the mole concept early, since these underpin almost every other topic, then move on to the more calculation-heavy quantitative and organic chemistry content.
