What happens when copper sulphate reacts with iron nail?
Explanation. When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed in the surface of iron and the colour of copper sulphate solution changes from blue to pale green.
What is the equation of an iron nail in copper sulphate?
This reaction is called displacement reaction in which the reactive element Iron, Fe has displaced less reactive Copper from its solution, The chemical equation can be written as: Fe+CuSO4→Cu+FeSO4.
What will happen if an iron nail is dipped into a solution containing copper II sulfate if a reaction occurs write its equation?
In this reaction, metallic iron is converted into ferrous ion (Fe2+) and cupric ion (Cu2 +) is converted into metallic copper. Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s). 1.
Why does the colour of cuso4 change when iron nail is dipped in it?
If an iron nail is dipped in the copper sulphate solution then iron displaces copper from the copper sulphate because iron is more reactive than copper. Therefore the colour of the copper sulphate solution changes.
What is the chemical equation of iron nail?
Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s). 1. Take two iron nails and clean them with a sand paper.
What is the chemical formula of rust?
Rust is hydrated ferric oxide and its chemical formula is Fe2O3. xH2O. The generic name of a very common compound, iron oxide, is rust.
What happens when an iron nail is dipped in copper sulphate solution Why does the colour change?
Which product is formed when cuso4 reacts with iron?
iron displaces the copper atom from copper sulphate to form ferrous sulphate. In this reaction, the Cu is reduced with a gain of electrons.
What is observed when an iron nail is put in CuSO4 solution for few hours?
We will observe a shift of colour from blue to green when immersing iron nails in the CuSO4 solution and a brown deposit will be observed on the iron nails.
When an iron nail is dipped in copper sulphate solution and kept undisturbed for half an hour or more?
When an iron nail is dipped in copper sulphate solution and kept undisturbed for half an hour or more, then the colour of the solution turns from blue to green because iron sulphate solution forms. A brown layer is deposited on the nail because copper deposited on the nail.
Is this reaction possible why or why not FE cuso4 feso4 Cu?
Answer. No because this reaction is occurring due to the fact that iron is more reactive than copper.
What type of reaction is Fe CuSo4 -> FeSo4 CU?
displacement reaction
Fe + CuSO4(aq) → FeSO4(aq) + Cu(s) The type of reaction is a displacement reaction. In this reaction, the highly reactive metal iron replaces the Copper in copper sulphate by giving up two electrons and gets oxidized and forms a new compound called ferrous sulphate.
