A 1.00 L solution contains 0.050 M NaCl and 0.050 NaBr. What is the solution concentration of chloride if 0.040 moles of AgNO3 is added? Assume that the total solution volume remains constant and Ksp AgCl = 1.77 x 10-10 and Ksp AgBr = 5.4 x 10-13. Our teacher never gave us a problem that had two Ksp, kinda threw me off.
