Which metals are extracted by electrolysis and cannot be reduced by CO2 or CO ?
Group I metals of reactivity series
Group II metals of reactivity series
Metals present above Carbon
Transition metals present in reactivity series
Metals above Carbon are usually extracted by electrolysis and cannot usually be extracted by carbon or Carbon monoxide.
Statement 1: It is comparatively easier to extract the metals that are present at top of the reactivity series than the metals present at the bottom of the reactivity series. Statement 2: Metals at the top of the reactivity series are highly reactive in comparison with the metals at the bottom.
Aluminium is obtained by the electrolysis of molten aluminium oxide. A metal just below aluminium in the reactivity series can be extracted by which method easily:
