What is the silver ion concentration in a solution prepared by mixing 50.0 mL of 0.496 M silver nitrate with 50.0 mL of 0.387 M sodium carbonate? The Ksp of silver carbonate is 8.1 x 10-12. You may ignore autoprotolysis and the acid-base behavior of carbonate ion Ag2CO3(s) 2AgCO3 First find the composition of the solution after Na2CO3 and AgNO3 have had the opportunity to react to form some Ag2CO3. What is the limiting reagent? 50.0 mL x 0.496 mol AgNO2 x 1 mol CO3 322.4 mmol Co3 needed 2 mol AgNO3 50.0 mL 0.387 mol Na2CO3 x 1 mol СОЗ-- 1 mol Na2CO3 x 19.35 mmol CO32-present So, Ag is the limiting reagent and (19.35-12.4) 6.95 mmol CO3 will remain after reaction, producing a carbonate concentration of 6.95 mmol/100. mL 0.0695 M. Now ICE table! 2Ag + 2 СОЗ 0.0695 M +X 0.0695 + X Ag2CO3 - +2x 2x KspAgTtco21 (2x)(0.0695 + x) We can simplify things if we assume x<<0.0695, then Ksp (2x) (0.0695) 4(0.0695) Ag1 2x1.08 x 10° M Checking our assumption, to 3 sig figs, 0.000108<0.0695!
