1.)What anion would ou add to only precipitate Fe^3+? OH^- Ksp Fe(OH)3 = 2.8×10^-39
Ba(OH)2 soluble (just so not too high a pH)
2.) what anion would you add only to precipitate Ba^2+? SO4^2- Ksp BaSO4 = 1.1×10^-10
Whoa look at the solubility of Fe2(SO4)3!

We just did this lab last week! These questions are based of the information you gathered during lab so your answer could be different based on what your lab instructor told you to do.
1.) According to our results it was Br^-
2.) Again, according to our results it would be SO4
Source(s): I'm in General Chemistry II and Lab. We did this lab last week.
