Which is more soluble Mg(oh)2 or. Ba(oh)2
While comparing solubility do we compare Ksp(solubility product values) or solubility (s) value
The lattice energy decreases more rapidly than the hydration energy going down the group which results in increased solubility down the group. For example,
Solubility order: LiF < NaF < KF; Mg(OH)2 < Ca(OH)2 < Ba(OH)2
The relation between solubility and the solubility product constants is that one can be used to
find the other. In other words, there is a relationship between the solute's molarity and the
solubility of the ions because Ksp is literally the product of the solubility of each ion in moles per
liter.
For example , if we wanted to find the Ksp of a slightly soluble compound from its solubility, we
would first have to make sure to correctly convert the (mass/ some volume) to (mols/liters) to
find the molarity of each ion. After we find the molarity of each ion (molar solubility) we can
plug these numbers into the Ksp formula which is the product of the solubility of each ion.
Ksp (Solubility product constant) is the equilibrium between a solid and its respective ions in a
solution. The value of the constant identifies the degree of which the compound can dissociate in
water.
Ksp is used to describe the saturated solution of ionic compounds.
