Question

\((\mathrm{Ag}+\mathrm{Pb})\) alloy \(\frac{\text { Melt and }}{\text { Zine is added }}\)
\((\mathrm{Ag}+\mathrm{Pb}+\mathrm{Zn})\) melt \(\stackrel{\text { Cool }}{\longrightarrow} \frac{\text { Layer } \mathrm{X}}{\text { Layer } \mathrm{Y}}\)
Select correct statement based on above scheme.
(a) Layer \(X\) contains \(Z n\) and \(A g\)
(b) Layer \(Y\) contains \(P b\) and Ag but amount of silver in this layer is smaller than in layer \(X\)
(c) \(X\) and \(Y\) are immiscible layers
(d) All are correct statements

Answer 1

Correct option: (d) All are correct statements

Explanation: Zinc and lead in molten state are immiscible and form separate layers, further Zn, being ligher, forms upper layer. Silver is soluble in both Zn and Pb, and hence all statements are correct.
