# How is Ksp related to molarity?

Nov 10, 2014

${K}_{s p}$ is related to molarity as follows:

For a saturated solution where an ionic solid such as silver chloride is in equilibria with its aqueous ions we can write:

$A g C {l}_{\left(s\right)} r i g h t \le f t h a r p \infty n s A {g}_{\left(a q\right)}^{+} + C {l}_{\left(a q\right)}^{-}$

For which ${K}_{s p} = \left[A {g}_{\left(a q\right)}^{+}\right] \left[C {l}_{\left(a q\right)}^{-}\right]$

This relationship is temperature dependent.
