Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion : \(ZrI_4\) is useful in purification of zirconium (Zr).
Reason : \(ZrI_4\) sublimise at room temperature.
In the light of the above statements, choose the correct answer from the options given below
Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion : \(ZrI_4\) is useful in purification of zirconium (Zr).
Reason : \(ZrI_4\) sublimise at room temperature.
In the light of the above statements, choose the correct answer from the options given below
- If both assertion and reason are true and reason is the correct explanation of assertion
- If both assertion and reason are true but reason is not the correct explanation of assertion
- If assertion is true but reason is false
- If both assertion and reason are false
The Correct Option is C
Solution and Explanation
Answer (c) If assertion is true but reason is false
Assertion : \(ZrI_4\) is useful in purification of zirconium (Zr). (correct)
Reason : \(ZrI_4\) sublimise at room temperature. (Not True)

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
