Consider three metal chlorides

x, y

and z , where x is water soluble at room temperature,

y

is sparingly soluble in water at room temperature and z is soluble in hot water.

x, y

and z are respectively

Answer: (D)

Solution

A chloride freely soluble in cold water fits

x

, and

CuC l_{2}

dissolves readily at room temperature. A chloride only sparingly soluble at room temperature fits

y

, and

AgCl

is almost insoluble. A chloride sparingly soluble in cold water but soluble on heating fits

z

, and

PbC l_{2}

dissolves in hot water. Hence

x

y

and

z

are

CuC l_{2}

AgCl

and

PbC l_{2}

respectively.
