Calculate the molar solubility of MgCO3 in a solution that already contains 1.7×10−3 M sodium carbonate.
MgCO3 Ksp = 6.82 x 10-6

IMPORTANT NOTE: You must use the quadratic equation to solve this problem.

  • Chemistry - ,

    .........MgCO3 ==>Mg^2+ + CO3^2-
    I........solid....0.......0.0017
    C.......for x.....x.........x
    E.......solid.....x.........x+0.0017

    6.82E-6 = (x)(0.0017+x)
    Solve for x = solubility in mols/L.
