5 Stars for showing work. A solution prepared by mixing 57.1 mL of 0.200 M AgNO3 and 57.1 mL of 0.200 M TlNO3 was titrated with 0.400 M NaBr. The solubility constant of TlBr is Ksp = 3.6 × 10-6 and the solubility constant of AgBr is Ksp = 5.0 × 10-13. Determine the range of NaBr volumes over which each solid precipitates.
