To determine the solubility product, Ksp, for Ag2CO3, 1.00 mL of 1.00 mol/L Na2CO3(aq) and 1.00 mL of 0.100 mol/L AgNO3(aq) were combined. The mixture was stirred for 10 minutes to ensure that equilibrium had been reached. A voltaic cell was constructed to determine the concentration of soluble Ag (aq) ions left in solution at equilibrium, and [Ag leg was thus found to be 2.0 x 10-7 mol/L. Calculate the equilibrium concentration of CO32-(aq) ions left in solution at equilibrium,...
