Charges on the metal MgSO4 = +2 NiSO4*6H2O = +2 CoCl2*6H2O = +2 KCr(SO4)2*12H2O = +3 CuSO4*5H2O = +2 (NH4)2Cr2O7 = +2 FeSO4*7H2O = +2 MnCl2*4H2O = +2 FeCl3*6H2O = +3

okay. Is it okay if I post some questions with my answers and you can check them to see if they're right?
February 29, 2012

chemistry
okay, so in FeCl3*6H2O the charge would be +3?
February 29, 2012

chemistry
So, for NiSO4*6H20 the charge is +2, as well as for CoCl2*6H2O? Or does the H2O play a role in the charge of the metal?
February 29, 2012

what are the charges on the metals? MgSO4 NiSO4*6H2O CoCl2*6H2O could you just explain how you determined the first one? I can take it from there.
