Okay, let's take the basics:
There is no such thing as "copper sulfate baking powder", as it would be poisonous.
I can think of no way to relate elemental nickel to the fictitious "copper sulfate baking powder".
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 cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
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.
A common electroplating solvent is a solution of the metal salt that will be deposited onto the object being plated. Common examples include copper sulfate for copper plating, nickel sulfate for nickel plating, and silver nitrate for silver plating.
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.
No, copper II sulfate is not magnetic because it does not contain any magnetic elements in its chemical composition. Magnetic properties are typically observed in metals like iron, nickel, and cobalt. Copper II sulfate is a compound of copper, sulfur, and oxygen, which do not exhibit magnetic behavior.
Nickel sulfate is an ionic compound though it has covalent bonds within the sulfate ion itself.
The compound NiSO4 7H2O is magnesium sulfate heptahydrate. It is a type of inorganic salt that is commonly known as Epsom salt.
nickel (ll) sulfate heptahydrate
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.
The equivalent weight of nickel sulfate is calculated by dividing the molar mass of the compound by the change in oxidation state of the element of interest during a specific reaction. For nickel sulfate (NiSO4), the equivalent weight of nickel is 58.7 g/mol as the molar mass of nickel is 58.7 g/mol and it has a +2 oxidation state in nickel sulfate.
Nickel (II) sulfate forms ionic bonds. In this compound, nickel (Ni) donates electrons to the sulfate (SO4^2-) ion, creating electrostatic attractions between the positively charged nickel ions and the negatively charged sulfate ions.
