When nickel is put in a copper (II) sulfate solution, a displacement reaction occurs where the nickel replaces the copper in the solution. This results in the formation of nickel sulfate and copper metal deposits on the surface of the nickel.
Nickel sulfate is an acidic compound because it contains sulfate ions which are derived from sulfuric acid. When dissolved in water, nickel sulfate will produce a solution that is slightly acidic.
When nickel sulfate is put into water, it dissociates into its ions - nickel (II) ions and sulfate ions. These ions then interact with water molecules through hydration to form a homogeneous solution.
A cobalt sulfate solution is typically blue in color.
No, storing a 1M copper sulfate solution in a nickel vessel is not recommended. Copper sulfate can react with nickel to form undesirable compounds, contaminating the solution. It is best to store the solution in a container made of a non-reactive material such as glass or polyethylene.

The flame color for nickel sulfate is green. The green color is due to the presence of nickel ions in the compound.
A dissolved sulfate ion is colorless. In solution, sulfate ions do not impart any color to the solution.

Iron III sulfate solution is typically pale yellow in color.

When iron (Fe) is dipped into a nickel(II) sulfate (NiSO4) solution, a displacement reaction occurs. The equation for this reaction is: [ \text{Fe (s)} + \text{NiSO}_4 \text{(aq)} \rightarrow \text{FeSO}_4 \text{(aq)} + \text{Ni (s)} ] In this reaction, iron displaces nickel from the nickel sulfate solution, forming iron(II) sulfate and solid nickel.
The sulfate ion itself does not contribute color to a solution, but the accompanying cation may contribute color.
Iron sulfate solution typically appears pale green or pale blue in color.
