Chapter 13.6, Problem 45PP

Interpretation Introduction

Interpretation:

The numerical value of K_spfor BaSO₄ should be determined.

Concept Introduction:

The solubility product constant, K_spis defined as the solubility product expression for the dissolved ions concentrations of a substance raised to the power of their stoichiometric coefficients.

For a substance:

  ${\text{M}}_{\text{x}}{\text{N}}_{\text{y}}\text{(s)}\rightleftarrows {\text{xM}}^{\text{y+}}\text{(aq)}\text{+}{\text{yN}}^{\text{x-}}\text{(aq)}$

The solubility product is given as:

  $K_{sp}={{\text{[M}}^{\text{y+}}\text{]}}^{\text{x}}{{\text{[N}}^{\text{x-}}\text{]}}^{\text{y}}$
