Vedclass · Answer

(D) The $Parkes$ process is a pyrometallurgical industrial process for removing silver from lead during the production of bullion.It is an example of liquid-liquid extraction.The process takes advantage of two liquid-state properties of zinc.The first is that zinc is immiscible with lead,and the other is that silver is $3000$ times more soluble in zinc than it is in lead.When zinc is added to liquid lead that contains silver as a contaminant,the silver preferentially migrates into the zinc.Because the zinc is immiscible in the lead,it remains in a separate layer and is easily removed.
