Essential Chemistry for IGCSE - Metal Extraction (Section 4 - No. 19)
Which of the following statement(s) about the reactivity series is correct?
Metals at the top of the series are the most reactive.
The reactivity series lists metals in order of increasing reactivity.
Carbon is used to extract metals below it in the series.
Metals in the reactivity series that are low can be extracted via electrolysis.
Explanation
The reactivity series lists metals in order of decreasing reactivity. Carbon can be used to extract metals lower in the series from their oxides or by electrolysis.
