Question

$K_{sp}$ of $Fe{\left(OH\right)}_3$ ____ ( greater/less) than $K_{sp}$ of $Fe{\left(OH\right)}_2$

Answer 1

$K_{sp}ofFe(OH{)}_3=[Fe\left]\right[OH{]}^3$

$K_{sp}ofFe(OH{)}_2=[Fe\left]\right[OH{]}^2$

we know the X power of 3 is more than X power of 2

so the Ksp of $Fe({OH)}_3$ is more than $Fe(OH{)}_2$
