Question

What is the relationship between Ksp and solubility (x) for magnesium perchlorate?

Answer 1

The relationship between $K_{sp}$ and solubility is important between slightly ionic compounds. Solubility is the maximum possible concentration of a solute in a solution at a given temperature and pressure. The equilibrium involved in determining slightly soluble solids at a given temperature and pressure is given by the equation below.

$M_pX_{(aq)}\leftrightarrow$ $pM^{m+} _{(aq)} +qX^{n-}_{(aq)}$

In this case, the solubility product is calculated by taking the solid's solubility expressed in units of moles per litre (mol/L) which is the molar solubility.

Magnesium perchlorate($Mg(ClO_4)_2$

Is a highly soluble ionic compound which easily dissolves in both polar and non polar solvents. The $K_{sp}$ Of the compound is increased due to it's increased polarity.
