Solubility Product Summary

Salt	Formula	Ksp Expression	s in Pure Water
AgCl	$Ag^{+}$ + $Cl^{-}$	[ $Ag^{+}$ ][ $Cl^{-}$ ] = $s^{2}$	s = √Ksp = $1.34 \times 10^{-5}$ M
$Ag_{2}CrO_{4}$	2 $Ag^{+}$ + $CrO_{4}^{2-}$	[ $Ag^{+}$ ]^{2}[ $CrO_{4}^{2-}$ ] = 4 $s^{3}$	s = (Ksp/4)^(1/3)
$BaSO_{4}$	$Ba^{2+}$ + $SO_{4}^{2-}$	[ $Ba^{2+}$ ][ $SO_{4}^{2-}$ ] = $s^{2}$	s = √Ksp
Ca(OH)_{2}	$Ca^{2+}$ + 2 $OH^{-}$	[ $Ca^{2+}$ ][ $OH^{-}$ ]^{2} = 4 $s^{3}$	s = (Ksp/4)^(1/3)
