OCR A and Supporting Chemistry Definitions

Match OCR A chemistry terms and useful supporting vocabulary to their definitions. Some entries extend beyond exact specification wording and are included to support understanding.

Choose a round length

Choose 10, 20, 30 or 40 pairs. This broad bank includes OCR A core terms plus clearly useful supporting chemistry vocabulary; it is not a list of 228 phrases that must all be memorised verbatim.

How the round works

Select one card from each column. Wrong attempts remain available and appear in the review at the end. Some terms share a definition or reagent set; the badge shows how many matches still use that card.
