The zinc is either contaminated with copper, or the copper is depositing so quickly onto the zinc that it is in a non crystalline structure and therefore appears to be black. Try melting some of the black stuff with a blowtorch and see what happens.
To change blue copper sulfate to white copper sulfate, you can heat the blue copper sulfate to drive off the water molecules and get anhydrous white copper sulfate. This process is known as dehydration. Be cautious when heating copper sulfate as it can release toxic fumes.
Yes, copper sulfate is an electrolyte. When dissolved in water, copper sulfate dissociates into copper ions and sulfate ions, which are capable of carrying an electric current.
The water solution of copper sulfate is acidic.
Iron is more reactive than copper, so when iron is added to copper sulfate solution, iron displaces copper in the reaction and forms iron sulfate. This process is known as a displacement reaction. This allows copper to be extracted from copper sulfate solution using iron.
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.
Copper sulfate is not a metal There are two compounds called Copper Sulfate, which are salts of the metal Copper. CuSO4 is Copper (II) Sulfate, once known as Cupric Sulfate. Cu2SO4 is Copper (I) Sulfate, once known as Cuprous Sulfate.
The zinc is either contaminated with copper, or the copper is depositing so quickly onto the zinc that it is in a non crystalline structure and therefore appears to be black. Try melting some of the black stuff with a blowtorch and see what happens.
Copper(II) sulfate changes from green to black when heated due to the decomposition of copper(II) ions to copper(I) ions, which are black in color.
The solute in a copper sulfate solution is copper sulfate (CuSO4).
The copper-to-sulfate ratio in copper(I) sulfate (Cu2SO4) is 2:1. This means that for every 2 atoms of copper, there is 1 sulfate ion present in the compound.
To change blue copper sulfate to white copper sulfate, you can heat the blue copper sulfate to drive off the water molecules and get anhydrous white copper sulfate. This process is known as dehydration. Be cautious when heating copper sulfate as it can release toxic fumes.
When black copper oxide is added to sulfuric acid, a chemical reaction occurs to form copper sulfate. The solution will have a blue color due to the presence of copper ions.

To obtain copper sulfate crystals from a mixture with sand, you can dissolve the mixture in water. The copper sulfate will dissolve, while the sand will not. You can then filter the solution to separate the sand from the copper sulfate solution. By evaporating the water from the copper sulfate solution, you can obtain copper sulfate crystals.
The word equation for copper sulfate and water is: copper sulfate + water → copper sulfate solution.
