Every deck we have for Chemical Changes, part of AQA GCSE Chemistry. 156 questions written against the published specification, free to study with no account. Each deck schedules its own reviews, so cards you find hard come back sooner than ones you have already got right.
Ordering metals by reactivity, how metals react with water and acid, and why some metals are extracted with carbon while others need electrolysis.
Oxidation and reduction in terms of oxygen and in terms of electrons, displacement reactions, and writing half equations. Includes Higher tier content.
The pH scale and what it measures, indicators, neutralisation as a reaction of hydrogen and hydroxide ions, and the difference between strong, weak, concentrated and dilute.
The three reactions of acids and the salts they produce, naming salts from the acid used, and the required practical for making a pure dry sample of a soluble salt.
How electrolysis works, why ionic compounds must be molten or dissolved, and the extraction of aluminium including why cryolite is used and why the anodes wear away.
Predicting the products at each electrode in aqueous solutions, the required practical, and writing half equations. Half equations are Higher tier.
Chemical Changes is one topic of AQA GCSE Chemistry. The other topics are all covered too, in the same format.
