Question

Match the column I with column II and mark the appropriate choice.

| Column I | Column II |
| A. Self reduction | P. Lead |
| B. Carbon reduction | Q. Nickel |
| C. Thermal decomposition of its carbonyl | R. Copper |
| D. Decomposition of its iodide | *. Titanium |

Answer 1

Correct option (c) : A – P, R; B – P, R; C – Q; D – S

Explanation:

Self reduction and carbon reduction are carried out in case of Pb and Cu. Ni is purified by the thermal decomposition of its carbonyl and Ti is purified by the decomposition of its iodide at higher temperature.
