Question $2(1$ point$)$

In a saturated solution of $Pb{l}_2(s)$ made by dissolving pure $Pb{l}_2(s),$ which of the

following statements is TRUE?

$[P{b}^{2+}]=0\mathrm{.}5[I^{-}]$

$\{\begin{array}{ccc}\text{:}[P{b}^{2+}]=\sqrt[\phantom{2}]{Ksp}& of& Pb{l}_2(s)\end{array}$

$\{\begin{array}{ccc}\text{:}[P{b}^{2+}]=K_{sp}& of& Pb{l}_2(s)\end{array}$

$[P{b}^{2+}]=[I^{-}]$
