Ni2(SO4)3
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
The formula for nickel II sulfate tetrahydrate is NiSO4 * 4H2O.
NiS is the formula for nickel sulfide. The nickel(II) ion has a 2+ charge and the sulfide ion is 2-. When the Ni(II)2+ bonds with the S2- the 2s cancel out and you are left with NiS (nickel sulfide). E. Morris
Stannous sulphate: SnSO4 Nickel sulphate: NiSO4.6H2O
Iron (II) sulfate is the correct name for this compound. The Fe ion has a charge of 2 and so does the sulfate ion, so there is no subscript after them.
nickel (ll) sulfate heptahydrate
The compound NiSO4 7H2O is magnesium sulfate heptahydrate. It is a type of inorganic salt that is commonly known as Epsom salt.
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
The chemical formula for nickel* (II) sulfate is NiSO4. *Note correct spelling.
Nickel(II) Sulfate Hexahydrate
The formula for nickel II sulfate tetrahydrate is NiSO4 * 4H2O.
Nickel(II) sulfate
Mercury, Iron or Nickel will not replace copper in a reaction between copper II sulfate and the metals because the metals are below copper in the reactivity level of the periodic table.
Ni(HSO4)2. Im positive
Nickel sulfate is an ionic compound though it has covalent bonds within the sulfate ion itself.
NiS is the formula for nickel sulfide. The nickel(II) ion has a 2+ charge and the sulfide ion is 2-. When the Ni(II)2+ bonds with the S2- the 2s cancel out and you are left with NiS (nickel sulfide). E. Morris
