Vedclass · Answer

(B) The cupellation process is a refining method used for the purification of noble metals like $Silver$ $(Ag)$ from base metal impurities like $Lead$ $(Pb)$. In this process,the impure metal is heated in a cupel (a shallow porous vessel) in a blast of air. The base metal impurities oxidize to form volatile oxides (e.g.,$PbO$),which are either absorbed by the cupel or blown away,leaving behind the pure noble metal.
