Question

$(Ag+Pb)alloy\stackrel{meltandaddzinc}{\to }(Ag+Pb+Zn)melt$ Select correct statement based on above scheme:

• A. Layer X contains zinc and silver
• B. Layer Y contains lead and silver but amount of silver in this layer is smaller than in the layer X.
• C. X and Y are immiscible layers
• D. All of the above are correct statements

Answer 1

The correct option is D All of the above are correct statements

Two layers X and Y are immiscible. X is the upper layer. It contains zinc and a large amount of silver. Y is the lower layer. It contains lead and small amount of silver. Thus, the quantity of silver in upper X layer is more than the quantity in lower Y layer. Thus, all the statements are correct.
