Question
Define: Acidic buffer solution. Write the relationship between solubility and solubility product for $PbCl2$
✓
Answer
Solubility equilibrium for $Pbl _2$, is given by,
$PbI _{2( s )} \rightleftharpoons Pb ^{2 \oplus}{ }_{( aq )}+2 I _{( aq )}^{\ominus}$
$\therefore x =1, y =2$
$\therefore K _{ sp }=(1)^1(2)^2 S ^{1+2}$
$\therefore K _{ sp }=4 S ^3$
The above expression shows the relationship between solubility and solubility product for $PbI_2.$
