Pearson Edexcel IAL Chemistry AS 1.3 Balanced & ionic equations
Pearson Edexcel IAL Chemistry AS 1.3 Balanced & ionic equations
Practise writing and selecting balanced full and ionic equations, including state symbols, spectator ions and formula accuracy.
How this is tested
- write balanced equations for decomposition, acid-carbonate reactions and combustion steps
- choose the simplest ionic equation by removing spectator ions and checking state symbols
- apply correct charges and formulae when forming ionic equations for precipitates or neutralisation
