Why does iron filings in copper sulphate solution become colourless from green after sometime?
Copper sulfate solution starts of a blue colour. When Iron metal is added to the solution a REDOX reaction begins in which the copper is reduced (gains electrons) to become copper metal and the iron is oxidised (loses electrons) to become iron ions. When the iron ions go into solution, it will change to a green colour which is the colour of iron (II) sulfate.
As a general principle, a more reactive metal will displace a less reactive metal from solution by the process described above.
What else can I help you with?
How make ferrous sulphate?
To make ferrous sulfate, also known as iron(II) sulfate, start with iron filings or iron sulfate heptahydrate crystals. Dissolve the iron source in sulfuric acid and oxidize it to form ferrous sulfate solution. Then, crystallize the solution to obtain solid ferrous sulfate crystals.
What happened when iron filings were added into the test tube that had water and copper sulfate in it?
actually, the real experiment is to have two test tubes, one with hot water and copper sulphate and other with vinegar and iron fillings. so you put two drops of the filings in the copper sulphate one and cover test tube with your thumb. then strike a match and keep it near the mouth of the tube, when pressure builds remove your thumb and it explodes. [ tiny explosion] But if u add water ,copper sulphate with iron fillings, then it turns all brownish and stuff, thats cuz the irons stronger then the sulphate or something... i hope it helped!!!
How do you separate a mixture of iron filings copper sulphate cystals and chalk powder?
Use a magnet to remove the iron filings from the mixture, then mix the remaining components with water. The copper sulfate will dissolve but the CaCO3 (chalk powder) will not. Filter the mixture to remove the chalk, then boil the water to recover the copper sulfate.
How will you separate the components of a mixtures containing sawdust sugar and iron filings?
You can separate the components of the mixture by using a magnet to separate the iron filings from the sawdust and sugar. You can then use a sieve to separate the sawdust from the sugar based on particle size differences.
What happens to iron when it reacts with copper sulfate?
A displacement reaction takes place. Iron being a more reactive element than copper displaces copper from its compound. Ferrous Sulphate which is green in color and copper a reddish brown element are formed. So, blue color of copper sulphate fades away and the solution becomes light green. Copper is deposited on the grayish iron filings.
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.

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
Could separate iron filings from copper sulphate and copper oxide with a magnet?
Yes, a magnet would remove the iron filings without attracting the copper salts, copper salts are not magnetic.
Is iron filings and sand a mixture or a solution?
It is a mixture

Is iron filings a mixture or solution?
Neither, it isn't soluble.
Is chili powder and iron filings a solution or a mixture?
Mixture!:)
Why colour of copper sulphate solution changes to light green when iron filings are added?
The color change occurs because the iron filings react with copper sulfate, forming iron sulfate and copper. This reaction results in a displacement reaction, where the iron displaces the copper in the compound. This changes the chemical composition of the solution, resulting in a light green color.
When a mixture of iron filings and sulfur is put in carbon disulphide in a test tube what can be observed?
When a mixture of iron filings and sulfur is put in carbon disulphide in a test tube, the sulfur will dissolve in the carbon disulphide, leaving behind the iron filings. The iron filings can be separated from the solution using a magnet.
How will separate the components of a mixture containing sawdust sugar and iron filings?
Use a magnet to separate the iron filings, filter the remaining sawdust and sugar water solution, evaporate the water from the sugar water solution.
How do you separate a mixture of iron filings copper sulphate cystals and chalk powder?
Use a magnet to remove the iron filings from the mixture, then mix the remaining components with water. The copper sulfate will dissolve but the CaCO3 (chalk powder) will not. Filter the mixture to remove the chalk, then boil the water to recover the copper sulfate.
