A BaSO4 slurry is ingested before the gastrointestinal tract is x-rayed because it is opaque to x-rays and defines the contours
NNADVOKAT [17]

Explanation:

The given reaction equation is as follows.

         BaSO_{4}(s) \rightleftharpoons Ba^{2+}(aq) + SO_{4}^{2-}(aq)

The value of \Delta G^{o} = 59.1 kJ/mol

We know that ,

            \Delta G^{o} = -RT ln K_{sp}

 or,       ln K_{sp} = -(\frac{\Delta G^{o}}{RT})&#10;

                       = -(\frac{59.1 kJ/mol}{(8.314 \times 10^{-3} kJ/mol.K \times 310 K))}[/tex]  

            = -22.93

or,      K_{sp} = e^{-22.93}

                      = 1.1 \times 10^{-10}

      K_{sp} = [Ba^{2+}][ SO_{4}^{2-}]

Therefore,      [Ba^{2+}] =\sqrt{K_{sp}}

                                        = \sqrt{ 1.1 \times 10^{-10}}

                                         = 1.05 \times 10^{-5} M

Therefore, we can conclude that the value of [Ba^{2+}] in the intestinal tract is 1.05 \times 10^{-5} M.
