An acid is a proton donor, and a base is a proton acceptor. In this topic, a proton means H+\text{H}^{+}H+.
Step-by-step lessons covering Edexcel IGCSE Chemistry Acids, bases and salt preparations for IGCSE Chemistry. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. 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.
