Sally is goint to determine the quantity of MgSO4 by titrating the Mg2+ ions using EDTA. What is the concentration of Mg2+ (in mmol/L) in the sample if it takes 22.9 mL of EDTA solution with concentration of 0.01108 mol/L to titrate 50.00 mL of the sample to the endpoint? Note: each molecule of EDTA will complex with one Mg2+ion.

  • Chemistry -

    mL x M = millimoles Mg^+2.
    Then M Mg^+2 = millimoles/50
