What is the chemical formula for copper sulfide?
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper(II) sulfate. Remember that Copper sulfate contains Copper, Sulfate and Oxygen because anything ending with 'ate' therefore contains oxygen
What is the pink precipitate formed when iron is added to copper sulfate?
The pink precipitate is finely divided copper, reduced to its metallic form by displacement from copper sulfate by iron, which is higher in the electromotive series than copper. Iron sulfate remains in solution.
Chemical formula for copper II sulfide?
Copper(II) sulfate has the formula CuSO4.
Is copper sulphate a mixture or an element?
It is a compound. ---------------------------- Copper sulphate is a compound (a salt) made up of the elements Copper and Sulfur and Oxygen (CuSO4).
Why does copper sulfate and hydrochloric acid produce no precipitate?
All chlorides are fairly soluble, as are copper compounds. Sulfate ions are also relatively soluble as well, so there is nothing to precipitate (unless you cool the solution down a bit).
Is sodium sulfide plus copper sulfate equals copper sulfide percipitate?
Yes: If aqueous solutions of copper sulfate and sodium sulfide are mixed, copper sulfide will precipitate from the mixture.

What is the chemical equation for aqueous strontium sulfide and aqueous copper sulfate?
aqueous strontium sulfide
Does sodium phosphate and copper sulfate precipitate?
The formed copper(II) phosphate is insoluble in water.
What is the name of the compound with the formula Cu2S?
copper (I) sulfide Common name: Chalcocite. It is an important copper mineral ore that is opaque with a dark grey to black luster.
Why does copper sulfate and hydrochloric acid produce no precipitate?
All chlorides are fairly soluble, as are copper compounds. Sulfate ions are also relatively soluble as well, so there is nothing to precipitate (unless you cool the solution down a bit).
What happens when ammonia is added to copper sulfate?
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
Is sulfide an element or a compound?
A sufide is an anion form of the element sulfur. It can form compounds if it combines with other elements. Sulfide on it's own is not a compound, you need a prefix to that like Hydrogen Sulphide. Do not get this mixed up with a sulfate; you can get copper sulphate but not copper sulfide.
What is the precipitate formed when cacl2 and na2so4 are mixed?
CuSO4 +Na2CO3 = Na2SO4 + CuCO3. CuCO3 is a solid and green in colour. So one gets a green precipitate.
