An attempt is made to analyse barium gravimetrically by precipitating of BaF, with NaF2. Assuming that 200 mg sample of Ba2+ in 100 mL of solution is to be precipitated and the precipitation must be 99.9% completed. The solubility product of BaF, is 1.7 x 10-6. i. Determine the amount of Ba2+ that must remain in 100 mL of solution so that the precipitation 99.9% is completed (in mg mL-1). ii. Based on the following balanced chemical equation, calculate the concentration of F after the precipitation of BaF2. BaF, (s) == Ba?* (aq) + 2F¯(aq)
