Why copper cannot displace iron from iron sulphate solution?
Iron is more reactive than copper. In other words, compared to copper, iron is more stable in a compound while copper is more stable as a pure element than iron is.
Why is iron able to replace copper in copper sulfate?
Iron is more reactive than copper.
How can an iron knife electroplated with copper?
Iron is more reactive than copper and can displace copper from solutions; copper is deposited on the knife surface.
What mass of copper contains the same number of atoms as 68.7 g of iron?
63.55g or 63.55 grams
What happen when copper sulphate is stored in iron vessel?
Since iron is a more active metal than copper, the iron would replace the copper in the copper sulfate, forming iron sulfate, and releasing elemental copper. The copper will not shape itself into a copper vessel, so eventually, the iron sulfate would leak out of the iron vessel, and eventually, if there is enough copper sulfate, the iron vessel will cease to exist.

Why is iron able to replace copper in copper sulfate?
Iron is more reactive than copper.
Why can iron be used to get copper from copper sulfate solution?
Iron is more reactive than copper
Is the mass of an iron atom any different from the mass of a copper atom?
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
Why can iron be used used to get copper from copper sulfate solution?
Iron is more reactive than copper
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 doesn't react with iron sulphate but deposits copper in copper sulphate?
Iron is more reactive than copper.
How can an iron knife electroplated with copper?
Iron is more reactive than copper and can displace copper from solutions; copper is deposited on the knife surface.
Why copper is deposited on iron nail when dipped in copper sulphate.?
It is an electrochemical reaction. Iron is more reactive than copper, meaning it is more easily loses electrons to form a compound. So the copper essentially "steals" electrons from the iron. Forming copper metal and iron sulfate.
What mass of copper contains the same number of atoms as 68.7 g of iron?
63.55g or 63.55 grams
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.
Why can iron be used to get copper from copper sulfate?
Iron can be used to get copper from Copper Sulfate because it is more reactive than Copper (higher up in the reactivity series).
