AP EAMCET · Chemistry · General Principles and Processes of Isolation of Metals
Consider the following:
Statement-I : In the extraction of Al by Hall-Heroult process, pure \(\mathrm{Al}_2 \mathrm{O}_3\) mixed with \(\mathrm{Na}_3 \mathrm{~AlF}_6\) lowers its melting point and increases conductivity.
Statement-II : Zirconium metal is purified by zone refining method.
The correct answer is
- A Both statement-I and statement-II are correct
- B Both statement-I and statement-II are not correct
- C Statement-I is correct, but statement-II is not correct
- D Statement-I is not correct, but statement-II is correct
