Question

Match List I (Position of the metal in the Activity Series) with the List II (Related Reduction Process) and Select the correct option using the codes given below.

| List(Position of the Metal in the Activity Series) | List - II(Related Reduction Process) |
| A. The bottom of the series | I. Electrolysis |
| B. The top of the series | II. Reduction by heat alone |
| C. The lower regions of the series | III. Found in native state |
| D. The middle of the series | IV. Reduction using carbon or some other reducing agent |

1. A - II B - III C-IV D-I

2. A-II B- I C- IV D- III

3. A- III B - I C- II D- IV

4. A- III B - I C-IV D-II

Answer 1

Correct option: (3) A - III, B-I, C-II, D-IV

Explanation:

In metallurgical process metal is obtained from their ore on the basis of activity series of metal.

Metal present in the bottom of the activity series are least reactive therefore they are found in the native state.

The metal present in the lower regions of the activity series are less reactive therefore they are reduced by heating alone.

Metal present in the middle of the activity series are moderately reactive therefore they are reduced by using carbon or some other reducing agents.

Metals present in the top of the activity series are highly reactive therefore they cannot be reduced by using carbon or some other reducing agents or by heating. Such metals are reduced by using electrolysis.

Therefore, A - III, B-I, C-II, D-IV
