Vedclass · Answer

(A) The liquation method is used for the purification of metals that have low melting points $(m.p.)$ compared to their impurities.Lead $(Pb)$,tin $(Sn)$,and bismuth $(Bi)$ are metals with relatively low melting points.In this process,the crude metal is placed on a sloping hearth and heated.The metal melts and flows down,leaving behind the infusible impurities.Thus,both the Assertion and the Reason are correct,and the Reason correctly explains why these metals are purified by liquation.

Assertion : Lead,tin and bismuth are purified by liquation method.
Reason : Lead,tin and bismuth have low $m.p.$ as compared to impurities.
