TS EAMCET · Chemistry · General Principles and Processes of Isolation of Metals
Which of the following statements are correct related to metallurgy?
(A) In electrolytic refining of copper, pure \(\mathrm{Cu}\) is used as anode.
(B) Zone refining is based on the principle that impurities are more soluble in the melt than in the solid state of the metal.
(C) \(\mathrm{TiI}_4\) upon heating will give pure Ti.
(D) Very pure Zr may be obtained by galvanisation.
(E) In copper smelting, hot air is used to convert to \(\mathrm{CuSO}_4\).
The correct answer is
- A (a)
- B (b)
- C (c)
- D (d)
Answer & Solution
Correct Answer
(B) (b)
Step-by-step Solution
Detailed explanation
(B) Zone-refining is based on the principle that impurities are more soluble in the melt than in the solid state of the metal. In this process, a circular mobile heater is used which is fixed at one end of the rod. The rod is made up of the impure metal and convert into pure…
