JEE Main levelOne or more correct optionsDifficulty 2 of 3pb101

Which of the following statements about compounds of lead are correct?

A $PbCl X_{2}$ is sparingly soluble in cold water but dissolves in hot water.
B $PbI X_{2}$ is a yellow solid.
C $Pb (OH) X_{2}$ is amphoteric.
D $PbCl X_{4}$ is the stable chloride of lead and is the usual product of chlorination in solution.

Answer: A, B, C

PbCl X_{2}

is a white solid more soluble in hot water.

PbI X_{2}

is yellow and crystallises as golden spangles from hot water.

Pb (OH) X_{2}

dissolves in acids and in excess alkali (forming plumbite).

PbCl X_{4}

is unstable and decomposes to

PbCl X_{2}

and

Cl X_{2}

, because of the inert pair effect. Statements 1, 2 and 3 are correct.
