If 0.10 M NaCl is added to a saturated solution of PbCl2 at 20°C, what will happen? Experiment Context (Thermal Solubility of Lead(II) Chloride): Chemistry students dissolved excess PbCl2(s) in 100 mL of distilled water across five temperatures, filtering and titrating dissolved lead ions to compute Ksp: Table 27: - 10°C: Solubility = 0.68 g/100mL; Ksp = 6.2 x 10^-6 - 20°C: Solubility = 0.99 g/100mL; Ksp = 1.6 x 10^-5 - 40°C: Solubility = 1.45 g/100mL; Ksp = 4.8 x 10^-5 - 60°C: Solubility = 1.94 g/100mL; Ksp = 1.1 x 10^-4 - 80°C: Solubility = 2.50 g/100mL; Ksp = 2.4 x 10^-4
