    We start with the solubility product expression for MnS.
    <br>Ksp = [Mn2+]* [S2-] = 3 * 10^-13
    <br>We then substitute what we know about the Mn2+ ion concentration into this equation and calculate the S2- ion concentration at which MnS just starts to precipitate.
    <br>[0.10]*[S2-] = 3 * ...
