A sample having a volume of 20.00 mL and containing 0.0500 M Hg2+ and 0.03250 M Bi3+ was titrated with 0.08300 M NazS to precipitate BizS3 and HgS. Ksp for HgS = 2x10-53 Ksp for BizS3 = 1x10-97 1. (f) (4 marks) At the first equivalence point in the above titration, will the second precipitate already start to form? Explain why or why not, and show all relevant calculations to derive your answer.
