Coordination Compound Charges

[Jasmine 2C]

For coordination compounds like in question 9C3 (Use the information in Table 9C.1 to write the formula for each of the following coordination compounds: (a) potassiumhexacyanidochromate(III) (b) pentaamminesulfatocobalt(III)chloride (c) tetraamminediaquacobalt(III) bromide (d) sodiumbisoxalato(diaqua)ferrate(III)), do we always want the overall charge to be neutral?

[Nohemi Garcia 1L]

For these sets of problems, yes we want their overall charge to be neutral. Just remember that the coordination compound/ligands must have a charge opposite to the "outside" ion.

[Arianna Perea 3H]

whats the oxidation charge of SO4?

[Veronica_Lubera_2A]

SO4-2 is sulfate, (so it has a -2 charge).
