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

Why are iron filings used to find the magnetic field when copper filings are not?
Copper filings are not attracted to a magnet, as iron filings are.
What is the separation method for iron filings and sulphur to obtain iron filings?
magnetic separation.
Can salt and iron filings be separated by physical means?
A magnet should be very good at picking out the iron filings.
Why do iron filings do not sink when placed slowly on the surface of the water?
Surface tension supports the filings in the same way as a pond skater. Add a drop of detergent and the meniscus is broken down and the filings fall to the bottom
What are the properties of iron filings?
iron
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.
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 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.
Why are iron filings used to find the magnetic field when copper filings are not?
Copper filings are not attracted to a magnet, as iron filings are.
What is the difference between cross filings and draw filings?
cross filings remove materials and draw filings smooths it down that's what i read anyway
What is a word equation for the single-displacement reaction of iron and copper sulfate?
The iron will displace the copper as it is more reactive. here's the equation: iron + copper sulphate = iron sulphate +copper
What is the density of aluminum filings?
The density of pure aluminum is 2.7.Filings have a packing ratio of roughly 0.6 so the density of the filings is about 1.6. this of course depends greatly on the size and shape of the filings.
Why colour of copper sulphate solution changes to light green when iron filings are added?
When an iron nail is dipped in the copper sulfate solution then iron displaces copper from the copper sulfate because iron is more reactive than copper.
How do you separate sand iron filings naphthalene ball and sodium chloride?
Iron filings removed magnetically. Water will dissolve sodium chloride and suspend sand. Sand can be filtered out of the solution, and salt reovered by evaporation of water. Naphthalene can be removed separately if necessary by solution of mixture in alcohol.
What is the separation method for iron filings and sulphur to obtain iron filings?
magnetic separation.
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.
