What will be the result if 100 mL of 0.06 M Mg(NO 3)2 is added to 50 mL of 0.06 M Na2C2O4? Assume the reaction is taking place at 25°C.
Substance Ksp, 25°C
MgC2O4(s) 8.6 x 10 –5
A) No precipitate will form.
B) A precipitate will form and an excess of Mg 2+ ions will remain in solution.
C) A precipitate will form and an excess of C2O42– ions will remain in solution.
D) A precipitate will form, but neither ion is present in excess.
