Assertion Metals of high impurity are obtained by zone-refining. Reason Impurities in the ore are more soluble in the metal than in the pure metal Choose the correct option.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Assertion is incorrect but Reason is correct
Step-by-step solution
Zone refining is a purification process that produces high-purity metals, not metals with high impurity. Thus, the assertion is false. The reason correctly states the underlying principle: impurities are more soluble in the molten metal than in the solid pure metal, allowing their separation during zone refining.
