    Exclamation Chemistry issue

    Uh, quick question. What would be the correct formula for Cobalt (II) Chlorate? I have Co(ClO3).Why would the parenthesis be used in this situation. In general?

    In addition, I'm stuck on the nomenclature for CrPO4. I'm geussing that it's chromium phosfate, but I can't figure out chromium's charge.

    And finally, I am studying for a High School (11th grade) test on nomenclature and chemical reactions. Please help, it would be greatly appreciated.

    We know that cobalt is given as \text{Co}^{2+} and chlorate refers to a group of atoms with an overall negative charge, i.e. \text{ClO}_3^-

    So we know two chlorates is needed to combine with \text{Co}^{2+} to give a neutral compound: \text{Co}\left(\text{ClO}_3\right)_2

    As for \text{CrPO}_4, the phosphate ion is also polyatomic like chlorate and has an overall charge of -3, i.e. \text{PO}_4^{3-}.

    Since only one chromium ion is needed to take out the charge, that must mean its ion has a charge of +3. So, the nomenclature for the compound must be chromium (III) phosphate.

    Tank You!

    Thank you uh, 0_o. I feel a bit dumb now that I look at it. Must've been a bit spaced yesterday.
