    Which ions?

    :biggrin: Hmm, oxidation states are the charge numbers you ascribe to atoms when you're doing redox-reactions, right?

    Which ions?

    Thanks for taking you time. Here goes: 1. (a) KCl \rightarrow K^+ + Cl^- (b) Na_2CO_3 \rightarrow 2Na^+ + {CO_3}^{2-} (c) BeO \rightarrow Be^{2+} + O^{2-} (d) Mg(NO_3)_2 \rightarrow Mg^{2+} + 2{NO_3}^- 2. (a) MgCO_3 (b) LiF (c) Zn(NO_3)_2 (d) Cu\text{(II)}O (e)...

    Which ions?

    Thanks, Bob. It's really helpful, since most of the ions we encounter belong to Group 1 or 2. But what about Fe (group 8), Cu and Ag (group 11) and Zn (group 12), which are ions I frequently encounter. Any scheme here?

    Which ions?

    Hi, I am told that \text{BaCO}_3_{(s)} is sparingly soluble in water with a solubility product K_{sp} = 8.1\cdot10^{-9}~M^2. I have to write the expression for the solubility product, but how do I know which ions Ba and CO3 forms (e.g. Ba^{+},~Ba^{2+},~Ba^{3+},\ldots). I happen to know that...
