Select correct statement regarding silver extraction /
purification process.
Show answer and solution
(1) Cupellation is used when lead is present in traces.
(2) In argentiferous lead the silver is removed by Parke's process
because silver has higher solubility in molten zinc than lead.
(3) Silver has higher solubility in molten zinc than lead and thus
forms zinc-silver alloy from which zinc can be distilled off leaving
behind the silver.
(4) Silver has higher solubility in molten zinc and thus forms
zinc-silver alloy from which zinc can be distilled off leaving behind
the silver.
