Which of the following statements is not correct?

$\begin{array}{1 1}\text{Lead(II) chloride and lead(II) iodide are soluble in hot water but crystallize out on cooling}\\\text{Lead(IV) chloride cannot be separated from the solution as it readily decomposes to lead(II) chloride and chlorine}\\\text{Lead(IV) chloride is not readily hydrolysed by water}\\\text{Percent of lead(II) halides decreases with the increase in atomic number of the halogen}\end{array}$

Lead(IV) chloride gets rapidly hydrolyzed by water.
