Question

HELP!! im studying for my chem exam..

How does CuSO4 --become--> copper(II)sulfate

Answer 1

naming binary ionic compounds

Answer 2

isn't CuSO4 already copper (ii) sulfate?
It's made up of the ions Cu2+ and (SO4)2-

Answer 3

Cu means copper
S means Sulfur
O means oxygen
SO4 means sulfate

so CuSO4 means copper sulfate

it becomes copper (II) because the charge of copper is sulfate (it was cancelled because the charge of sulfate is also 2- so if you criss cross, they cancel)

does that help?

Answer 4

cuso4 is copper(II) sulphate. cu valency is 2+ and sulphate valency is 2-

Answer 5

Ohhhh okay so the initial was Cu(SO4)^2+and once balanced it goes to Cu(II)Sulfate4

Answer 6

All these responses were a very big help!

Answer 7

ahh yes that was what i mean...charge of copper is 2...which is same as sulfate so they cancelled
