copper sulfate
This is sodium sulphate.
Al2(SO4)3Aluminum Sulfate
mg+cuso4 gives mgso4+cu2+
Copper does not form +3 oxidation number. So there cant be a formula like that.
CuSO4 is made by the ions Cu2+ and SO4 2-.
Cu2 (SO4)3
SO4 is the chemical formula for the anion sulfate.
Cu2+ + (SO4)2- + Ba2+ + 2Cl- = Cu2+ + 2Cl- + BaSO4 (s)
This is sodium sulphate.
Al2(SO4)3Aluminum Sulfate
This is Aluminum sulfate.
Cu+H2SO4 Gives CU2(SO4)2+H2O+S2O2
mg+cuso4 gives mgso4+cu2+
Copper does not form +3 oxidation number. So there cant be a formula like that.
Cu2+ + I- --> Cu2I The compound created is Copper(I) Iodide
Fe2(SO4)3 is Iron (III) Sulphate.
Because in solution the ions Cu2+ and (SO4)2- are formed.
