SO3 is not magnetic. For a compound to be magnetic, it must contain iron, cobalt or nickel.
Yes.
hydroxic sulphate
calcium + copper sulphate = calcium sulphate + copper hydroxide
Iron(ii)sulphate = FeSO4
Aluminium Sulphate= Al2(SO4)3
Yes.
Iron is a magnet so it could be used for separating bits of metal from crushed up rock? True for iron, and separating bits of iron. But iron sulphate is not magnetic.
No. All metal sulphate are soluble in water, except barium sulphate, calcium sulphate and lead sulphate.
No
Ferrous sulphate, or iron (II) sulphate has the formula FeSO4.
the limit concentration of sulphate is 1000 ppm after that "sulphate resistant cement" should be used
Sodium + Sulphate + Water = Sodium Sulphate + Water
no reaction between ammonium sulphate and iron sulphate
vanadium(I) sulphate, but as far as I am aware, this compound is unknown
Yes, a magnet would remove the iron filings without attracting the copper salts, copper salts are not magnetic.
Zinc Sulphate : ZnSO4. In addition, Zn Sulphate may be in hydrated form as Zinc Sulphate monohydrate i.e. ZnSO4.H20 or Zinc sulphate heptahydrate i.e. ZnSO4.H2O
the aluminium is split with the sulphate ion. this leaves the sulphate on its own with a charge. the copper then takes the place of the aluminium turning the charge of the sulphate ion to neutral, this leaves the aluminium and copper sulphate.
