12. Name one metal each which is extracted by a)reduction with heat alone b)reduction with C c)reduction with Al. d)electrolytic reduction
Metal which occur low in reactivity series can be extracted by heating the ore alone. For example, mercury , copper etc.
Metal which are moderately reactive can be reduced using various reducing agents like carbon, aluminium.
Metals like zinc, iron etc can be extracted using carbon.
Metals like manganese, chromium etc can be extracted using aluminium.
The highly reactive metals like potassium, sodium etc. are extracted by their electrolytic reduction.
