Identify the process of refining to obtain pig tin.
1 Polling
2 Van Arkel method
3 Liquation
4 Mond's process
Explanation:
Pig tin is obtain by liquation process, in this technique for separating constituents of an ore, a metal or an alloy by partial melting. When the material is heated to a temperature, where one of the constituents melts and the other remains solid, the liquid constituent can be drained off. The pure metal (tin) flow down leaving behind the non-fusible material on the health.

The processes used in the refining of aluminum and zinc metals, respectively are
1 Cupellation and fractional distillation
2 Hoope's process and cupellation
3 Poling and fractional distillation
4 Hoope's process and fractional distillation
Explanation:
Cupellation: This method is applied when the impure metal contains impurities of other metals which form volatile oxides. Distillation process: This method is employed for purification of volatile metals like zinc, mercury, cadmium etc. The impure metal is heated in an iron and the vapours are condensed in separate receivers.

Which method is used for refining \(\mathrm{\mathrm{Zr}}\) and Ti?
1 Van arkel method
2 Mond's process
