OCR A Year 13 Transition Metals and Inorganic Chemistry
Transition elements, complex ions, colours, redox, qualitative analysis and catalysis.
Use the dedicated colours quiz alongside the transition-metal and qualitative-analysis practice on this page.
OCR A colour recall
Transition metal colours
Recall aqueous ions, hydroxide precipitates, ligand-substitution products and the written observations OCR A expects. Includes both species → colour and colour → species modes.
Active recall
Topic quizzes and chemistry games
Short runs give immediate reasoning; full runs retest anything missed.
