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.
Can you place silver nitrate solution in an iron vessel why or why not?
No. Iron is a more reactive metal than silver, so the iron will replace the silver in the silver nitrate solution, forming an iron nitrate solution and solid silver. Eventually, the iron container will be gone, its atoms having gone into the iron nitrate solution.
What happens when an iron nail is immersed in copper sulphate solution?
The iron is more reactive than copper so when the iron nail is immersed in copper sulphate the iron takes sulphate ion from the copper sulphate and copper metal is deposited on top of the iron so that the nail will then look like a copper nail.The chemical reaction is called a replacement reaction, and is chemically represented as : CuSO4(compound in solution) + Fe(metal) ------>Cu(deposited metal) + FeSO4.
Which of the following is an example of a solution Iron metal, iron ore, iron alloy, iron rust?
An iron alloy (Explanation): Iron metal is a pure substance, so it cannot be a solution, so it's not that one. An iron ore is found in nature and is iron chemically combined with other substances, so it's not a mixture because mixtures aren't chemically combined. Iron rust is also chemically combined iron with oxygen, so it's not a mixure. Therefore, the iron alloy is the correct answer (btw, an alloy is where you heat the metal to a liquid and mix in other metals like zinc to make pennies and stuff)
Is iron a non metal pr a metal?
Iron is a metal. And a solid
Is Iron metal an example of a solution?
No.
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 happens when iron is dipped in copper sulphate solution and why?
When Iron metal is dipped into a solution of copper sulfate a REDOX reaction occurs in which the Copper is reduced (gains electrons) and the iron is oxidised (loses electrons). When this happens, the iron metal becomes iron ions and the copper ions in the solution become copper metal. Cu2+(aq) + 2e- --> Cu(s) Fe(s) -->Fe2+(aq) + 2e- This occurs because the iron is a more active metal than copper, and as a general rule of thumb, a more reactive metal will displace a less reactive metal from solution. This principle underlies the action of the sacrificial electrode.

What happens with gold dipped in iron sulphate solution?
Nothing. Gold is a noble metal- it is not displaced by iron.
Why can iron be used to get copper sulfate solution?
Because iron is a more reactive metal than copper.
Reacting copper II sulfate with iron yields?
If an aqueous solution of copper(II) sulfate is contacted with metallic iron, at the least the surface of the iron passes into solution and is replaced by a layer of metallic copper. This is an example of displacement by a metal higher in the electromotive series than the metal it displaces.
When an iron nail is placed into a solution of copper sulfate what happens?
The iron which is a more electrochemically active metal gets plated with copper and iron sulfate is formed

Which metal is used in galvanizing?
It's zinc..which is used in galvanization!!
