Why is colour of copper sulphate blue?
The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
What is the colour of the solution if zinc is added to copper sulphate solution?
No colour
Which colour of copper sulphate solution change when iron dipped in it?
It may seem like the iron rusts, but it doesn't. The chemical formula for copper sulfate is CuSO4, or, 1 copper atom, 1 sulfur atom, and 4 oxygen atoms to each molecule. When the iron is placed in the solution of copper sulfate, it replaces the copper in the solution, turning copper sulfate into iron sulfate (FeSO4) and pure copper collects on the iron. This can be proved by removing the copper and seeing that the iron has lost a lot of its mass, as in, it lost mass to the copper sulfate. The iron (steel wool) takes on a pinkish color which is metallic copper deposited when the solution forms iron sulfate.
What will happen when iron and iron react?
Copper sulphate is a blue coloured solution. As soon as you react it with iron, you will notice that the solution is turning into light green which means iron sulphate solution is forming. Iron being more reactive than copper displaces copper from its soluion.
Why was it necessary to weigh the iron filings accurately though the mass of copper sulphate taken was only approximate?
it is because iron is solid and can easily sublimes in aqueous copper sulphate
When an iron nail is dipped into copper sulphate solution after sometime the colour is changed into?
When a iron nail is dipped into copper sulphate solution after sometime the colour is changed into pale green.
What two colour changes do you get when you add copper sulphate solution to iron wool?
When you add copper sulphate solution to iron wool. The iron wool turns copper in color and the copper sulphate solution turns pale blue as the iron displaces the copper from the copper sulphate solution forming iron sulfate.
Why does the color of copper sulphate change when an iron nail 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.
What happens when an iron nail is dipped in copper sulphate solution?
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
Iron plus copper sulphate equals iron sulphate plus copper - what change would you see on the surface of the nail?
The copper will appear on the surface of the nail, so it will be different in colour-it'll be like copper.
When copper sulphate reacts with iron what colour does it turn?
When copper sulphate reacts with iron, the solution turns blue due to the formation of copper ions in the solution. This is because copper is displaced from the copper sulfate and iron sulfate is formed, leading to the blue color of the solution.
What is reaction between iron and copper sulphate?
Iron(Fe) + Copper Sulphate(CuSO4) → Iron Sulphate(Fe2SO4) + Copper(Cu)[Displacement Reaction]
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.
What doesn't react with iron sulphate but deposits copper in copper sulphate?
Iron is more reactive than copper.
What is the word equation for iron sulphate and copper?
The word equation for the reaction between iron sulfate and copper is: iron sulfate + copper → copper sulfate + iron.
Why do you use copper sulphate?
A rather incomplete question. I could use copper sulphate for a number of reasons, for example as an electrolyte for copper plating, as a medium for growing impressive deep blue crystals, as a fungicide and so on. For fun, try dropping some iron filings into a fairly concentrated solution of copper sulphate and observe how the iron filings change to a copper colour and the solution changes to a green colour.
What is the word equation for iron and sulphate?
copper sulphate+iron+water
