What technique should be used when changing some copper sulfate solution into solid copper sulfate?
filtration
The blue colour of the solution fades during the electrolysis of copper sulfate. Explain why.?
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Insoluble base used to make copper sulfate?
copper (II) oxide
How do you mix copper sulphate with mercury?
Copper sulfate was used as a catalyst for the amalgamation of silver. We haven't now any other motivation to mix copper sulfate with mercury.
What are sodium hydroxide and copper sulfate used to test for?
protiens
Why can iron be used used to get copper from copper sulfate solution?
Iron is more reactive than copper
Why can iron be used to get copper from copper sulfate solution?
Iron is more reactive than copper
How can iron be used to get copper from copper sulfate solution?
Since iron (Fe) is more reactive than copper (Cu) it will be 'plated' with copper when the metal iron is stuck in copper sulfate solution. Fe(s) + Cu2+(aq) + [SO42-]aq ---> Fe2+(aq) + Cu(s) + [SO42-]aq
Why can iron be used to get copper from copper sulfate?
Iron can be used to get copper from Copper Sulfate because it is more reactive than Copper (higher up in the reactivity series).
Is copper sulphate used as an iron supplerment?
Since copper sulfate does not contain any iron it cannot be used as an iron suppliment. Copoer sulfate only contans copper, sulfer, and oxygen and has the formula of CuSO4
What technique should be used when changing some copper sulfate solution into solid copper sulfate?
filtration
How scrap iron is used to displace copper from solution?
In general, any metal higher than copper in the "electromotive series" will displace copper from copper sulfate solution. This category includes all the alkali and alkaline earth metals and other common metals such as iron and zinc. For example Aluminum and Iron both displace Copper: Aluminum in Copper sulfate will trade places in the ionic balance of the solution and 'join' with the sulfate. CuSO4(aq) + Al(s) ==> AlSO4(aq) + Cu++(s) Because this single displacement reaction occurs in immediate proximity to the aluminum, Copper++ ions accumulate in a fluffy rust colored fur around the aluminum. Iron in Copper Sulfate will also go into the aqueous sulfate solution and the Copper will precipitate onto the Iron CuSO4(aq) + Fe(s) ==> FeSO4(aq) + Cu?(s) This reaction happens at the ferrous surface more intimately than the Aluminum and the Copper is deposited as a 'plate'.

What method is used to separate copper from copper sulphate solution?
By heating copper sulfate is decomposed in copper(II) oxide and sulfur trioxide; by reduction of the copper oxide with hydrogen copper is obtained.
What substance turns Benedicts solution blue?
The Benedict solution contain copper(II) sulfate which is blue. The Benedict solution is used to test mono- and disaccharides.
Why will iron displace copper from aqueous solutions of copper salts?
Because iron is more reactive than copper. If iron displaces copper, that releases energy (enthalpy). If copper were to displace iron, that would require energy to be used. This is less favourable and , averaged over the huge number of molecules, atoms and ions in the solution, the more energy producing reaction is vastly preferred. Hence, iron put into copper sulphate solution gets coated in copper and the solution slowly loses its blue colour. But if you put copper metal in iron sulphate solution, nothing noticable occurs.
What are the materials used in capsule stain?
For the capsule stain Congo red or a Nigrosin solution can be used. Next, Maneval's stain is used.
