Question

10. Explain how the following metals are obtained from their compounds.
(i) Metal 'X' which is low in reactivity series.
(ii) Metal 'Y' which is in the middle of reactivity series.
(iii) Metal 'Z' which is high in the reactivity series.​

Answer 1

Answer:

1. by heating

2. by roasting

3. by electrolyses

Answer 2

1. metals low in reactivity series are obtained by the method of heating alone

2. metals in the Middle of the reactivity series are obtained by either roasting- sulphides are converted to oxides when heated in presence of oxygen

or

oxygen

3. electrolytic refining
