Reactivity series Flashcards – Cambridge IGCSE (9–1) Chemistry 0971 (Extended) (2026–2028)

Under comparable conditions, what reaction observations suggest that one substance is more reactive than another?

A more readily observed or more vigorous reaction suggests greater reactivity. A substance that reacts may also be ranked above one that does not.

How are experimental comparisons used to establish a reactivity order?

Combine the comparisons to arrange the tested substances from more reactive to less reactive.

What limits should be respected when inferring a reactivity order from experimental results?

Follow the evidence for the substances tested; do not assume every substance in the full reactivity series was tested.
