Chemistry - Metallurgy Question with Solution | TestHub
Consider the following statement -
(I) Impure nickel is purified by Van Arkel method
(II) Anglesite and Cerussite are the ore of same metal
(III) Matte is a mixture of
(IV) In hydrometallurgy, Zn is used as an oxidizing agent in the purification of Ag from
If 'T' is for true statement and 'F' for false statement then select CORRECT option :
Options:
Answer:
Solution:
Explain the question: Identify the correct True/False sequence for four metallurgical statements. Concept: Refining, Ores, and Extraction Principles.
Solution:
(I) False: Nickel is purified by Mond's Process. Van Arkel is used for Zr or Ti .
(II) True: Anglesite PbSO4 and Cerussite PbCO3 are both ores of Lead (Pb).
(III) True: Copper matte is indeed molten Cu2S with a small amount of FeS .
(IV) False: Zinc acts as a reducing agent (displaces Ag), not an oxidizing agent.
Final Answer : Option (B) (F T T F).
