    Describe an electrochemical cell that would determine the solubility product constant at equilibrium for Chronium (III) hydroxide, then calculate the solubility product constant.

    Balance these reduction potential half equations first:

    Ox. Cr+3(aq) + 3e => Cr(s) -0.74v
    Red. Cr(OH)3(s) + 3e => Cr(s) + 3OH-1(aq) -1.30v

    Ok first of all the reaction you write with Ox next to it is actually a reduction as written but that is fixed easily as :
    Ox. Cr+3(aq) + 3e < = Cr(s) ...
