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.
What happens when a mixture of sand and copper sulphate is stirred into water?
A solution is a mixture of any two substances, usually a liquid. Copper sulphate and water is a solution. There are many other solutions as well. Water and milk is a solution, mixing chemicals. Any mix of materials is technically a solution.
How many water molecules bound in copper sulfate?
The most common form is the pentahydrate.
If you needed to use powered copper 2 sulfate in an experiment and were only supplied with clumps of copper 2 sulfate which tool would you need to convert the copper sulfate to usable form?

How many molecules of water are in a copper sulphate crystal?
Each molecule of copper (II) sulfate pentahydrate (the blue form) contains 5 molecules of water.

Does a change in color observed when copper II sulfate crystals become dehydrated how do you account for the change when water is added to the heated copper II sulfate?
Yes, copper (II) sulfate, also known as cupric sulfate, is a deep blue when it is hydrated (when it has water). If you heat it, the water evaporates and leaves plain copper (II) sulfate power, which is a cream color. So yes, dehydrating copper (II) sulfate in its hydrated form will cause it to change from blue to white. If you take this dehydrated (anhydrous) copper (II) sulfate and add water to it, it will become hydrated again, so the white powder will, once again, turn that deep blue color.
What is solid copper sulfate?
Copper sulfate in the solid form are crystals
Is cupric sulfate blue?
Most people think that Cupric sulfate or Copper(II) sulfate, is blue in colour. But actually it is not. Blue colour in Copper(II) sulfate is due to the presence of Water molecules in it. This form is called Copper(II) sulfate Pentahydrate[CuSO4.5H2O], which most people see. If it does not have any water molecules in it, the thing is in pure state and is White in colour. This form is Anhydrous Copper(II) sulfate[CuSO4]. This form is rarely seen, because it can absorb water itself from the nature and become blue in colour. So from this we know that very pure Copper(II) sulfate is not blue, But its Pentahydrate form is blue.

What is Color of copper sulfate solution and ammonia?
Copper sulfate (II) CuSO4 is blue; ammonia is a colorless gas. If you mix ammonia water and copper sulfate solution, you will actually form a Brilliant blue copper-ammonium complex that is very pretty. Copper sulfate is blue by itself and anhydrous ammonia is a clear gas with a choking odor.
How many molecules of water are in a copper sulphate crystal?
Each molecule of copper (II) sulfate pentahydrate (the blue form) contains 5 molecules of water.
What happens when you heat anhydrous copper sulphate?
Copper sulfate is normally found in the form of blue crystals, copper (II) sulfate pentahydrate. When you heat copper sulfate pentahydrate it turns white as the water which is driven off by the heat. The white solid remaining is anhydrous copper sulfate. If you add water to the anhydrous copper sulfate an exothermic reaction occurs, you can feel the test-tube getting hot, as the blue copper sulfate pentahydrate is re-formed.
What do copper sulphate crystals contain?
Copper ions, Cu2+, sulfate ions, SO42- and in the most commonly encountered form,CuSO4.5H2O water =)
Why Hydrated copper sulfate crystals cannot be obtained from a solution by direct heating?
Heating the saturated solution of Copper sulfate will not form the hydrated copper sulfate crystals because only after cooling down the saturated solution of copper sulfate then only the crystals of the hydrated copper sulfate can be formed
