Question

A CHM 122 student considers an ionic compound M,X, that contains the metal cation M2 and the anion X.
7.
The student determines that the molar solubility of M,X, is 2.7 x 10mol/L.
What is the Kan value for this compound?
Type your answer in the space below using scientific notation.
(example: 0.012 = 1.2*10^-2)

Expert Solution

Introduction

Solubility product (K_sp) is an equilibrium constant that is the product concentration of ions. The molar solubility is the no. of moles of solute dissolved in a given volume of solution (in litres) before the saturation of the solution. Once it gets saturated, the solute added will precipitate out. Molar solubility is directly related to solubility product, the K_sp and can be given as:

${for the compound M}_{3} X_{2} M_{3} X_{2} → {3[M}^{2 +}] + {2[X}^{3 -}]^{2} K_{s p} = {{[M^{2 +}]}^{3} {[X}^{3 -}]}^{2}$
