The method of zone refining of metals is based on the principle of

greater noble character of the solid metal than that of the impurity

greater solubility of the impurity in the molten state than in the solid

greater mobility of the pure metal than that of impurity

higher melting point of the impurity than that of the pure metal

Verified by Experts

The correct Answer is:

The method of zone relining of metal is based on the principle of AIFMIT-2003)

greatermothilly of the pure metal from that of the impurity

Higher melting poibnt of the impurity then that of the pure metel

greaternoble churactior of the solid metal than that of the impurity

greater solubilly of the impurity in the molten state then the solid

impurities of low boiling metals can be separated by distillation.

impurities are more soluble in molten metal than in solid metal.

different components of a mixture are differently absorbed on an adsorbent.

Vapours of volatile compound can be decomposed in pure metal.
