I am working on this homework and not sure if I have the answers right or not. I want to make sure I am understanding this because this counts as a big part of my grade. I think the answer should be Rh(HSO4) right? I also had some other questions as well.

The valency of rhodium = 3 so the ion is Rh

^{3+}. The hydrogen sulphate ion is HSO_{4}^{-}. So putting these together gives us Rh^{3+}(HSO_{4}^{-})_{3}Notice the number of positive charges = number of negative ions in the formula

Thank you for this article. I really enjoyed reading this article.
