    Answer:

    Ksp=\frac{[Co^{2+}][S^{2-}]}{1}

    Explanation:

    Hello there!

    In this case, according to the given information, it turns out firstly necessary to  write the chemical equation for this reaction as shown below:

    CoS(s)\rightleftharpoons Co^{2+}(aq)+S^{2-}(aq)

    Thus, since solids are not included in equilibrium expressions, we can set this one up as follows:

    Ksp=\frac{[Co^{2+}][S^{2-}]}{1}

    Regards!
