Write down the dissolution equation for nickel(II) perchlorate dissolving in water. (Perchlorate is a polyatomic ion with the formula ClO41-.) If four moles of the ionic compound are dissolved, then how many moles of the ANION are present in the solution?

Perchlorates are generally soluble...

Explanation:

...and in water, would undergo ionization to give the aquated ion...

#Ni(ClO_4)_2(s) stackrel(H_2O)rarrNi^(2+) + 2ClO_4^(-)#

Given the formulation, if 4 moles of solute go up, there will be EIGHT moles of the anion in solution. I have a feeling that this solubility is a bit fantastic, even for a perchlorate.
