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.
Does iron and copper chloride solution react?
Yes, iron will react with copper chloride solution to form iron chloride and copper metal. This is a single displacement reaction where iron displaces copper from the chloride solution.
What metal can remove zinc from a solution?
A metal like iron or magnesium can remove zinc from a solution through a redox reaction where the more reactive metal displaces the less reactive zinc ions. For example, iron can displace zinc from a solution containing zinc ions to form iron ions and solid zinc.
What happens when iron is placed in copper sulfate solution?
When iron is placed in copper sulfate solution, a chemical reaction occurs where the iron displaces the copper in the solution, forming iron sulfate and copper metal. This is known as a displacement reaction.
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 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.

Why can iron be used to get copper from copper sulfate solution?
Iron can displace copper in a chemical reaction because it is a more reactive metal. When iron is added to a copper sulfate solution, the iron atoms will replace the copper atoms in the solution, forming iron sulfate and causing copper metal to be deposited. This process is known as a displacement reaction.
What happens with gold dipped in iron sulphate solution?
Nothing. Gold is a noble metal- it is not displaced by iron.
What is the reaction between iron and copper sulfate?
When iron is added to a solution of copper sulfate, a displacement reaction occurs where the iron displaces copper from the copper sulfate solution. This results in the formation of iron sulfate and copper metal. The iron gradually dissolves in the solution, while the copper metal precipitates out.
What is the reaction between silver nitrate solution and iron metal.?
When silver nitrate solution is reacted with iron metal, a displacement reaction occurs. The iron displaces the silver from the silver nitrate solution, forming iron(II) nitrate and solid silver. The balanced chemical equation for this reaction is: 2AgNO3 + Fe -> 2Ag + Fe(NO3)2.
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.
