I have spent about 3 days looking all over the internet trying to find the answer for this, and it's not in our textbooks either. And the only thing our teacher does is tell us if the answer we have is wrong, would anyone be able to help?
I'm look for a use for Copper (I) Sulphide, and another use for Copper (II) Sulphide.
Whenever I search the internet, I always get copper sulphate, but its not the same thing!
