Coistaht of Magnesium Carbonate DATA and CALCULATIONS Trial 1 Trial 2 i. Initial volume of Mgco, ral O-00 m Molarity ofEDTA 0.610 mt o- olo 3. Initial volume of EDTA 4. Final Volume of MgCO 5. Final volume of EDTA 6. Net Vol EDTA delivered 6.8 m ll-1 | 6 .016 rn-arol 7. Mol EDTA consumed. Show calculations 8. Mol Mg consumed 9. Net Vol Mgcoelivered6 10. Equilibrium concentration 1.12 of Mg2 in MgCO solution. Show calculations. 002 M 11. Equilibrium concentration of CO, in MgCO 10.00AM solution 12. Experimental Kg 13. Average Ks 0710 4. Accepted value ofKe | 4, o 10 5. Percent error

Explanation / Answer

percentage error = |[(Average Ksp experimental - Accepted value of Ksp)/Accepted value of Ksp]| x 100%

= |[(4.85 x 10-6 - 4 x 10-5)/(4 x 10-5)]| x 100%

= 87.875%
