Why will iron displace copper from aqueous solutions of copper salts?
Wiki User
∙ 12y ago
Because iron is more reactive than copper. If iron displaces copper, that releases energy (enthalpy). If copper were to displace iron, that would require energy to be used. This is less favourable and , averaged over the huge number of molecules, atoms and ions in the solution, the more energy producing reaction is vastly preferred. Hence, iron put into copper sulphate solution gets coated in copper and the solution slowly loses its blue colour. But if you put copper metal in iron sulphate solution, nothing noticable occurs.

What if membranes were made of salts and sugars?
Then they would disolve in water, and would be useless in conjunction with aqueous solutions.
What chemical system can Ksp be assigned?
Ksp or solubility product is meaured for aqueous solutions of salts, for acids is Ka , for bases is Kb and for water is Kw.
Are ammonia and copper mixed together a chemical?
1. Ammonia (gas, NH3) and copper (solid, Cu) cannot be mixed. 2. Ammonia can react with copper salts in water solutions.
Acids Bases Salts?
In water solutions salts may be acidic, basic or amphoteric.
Will there be a reaction if all reactants and possible products are aqueous while no insoluble salts precipitate are formed?
There will be no reaction if all the reactants and possible products are aqueous while there is no insoluble salts precipitate that are formed.
Is iron used to displace copper from solutions of its salts?
Yes, the iron is used to displace copper from solutions of its salts. c';
Is a nitrate aqueous or solid?
Nitrates are salts and generally form stable solids, they are generally soluble and form aqueous solutions.
What if membranes were made of salts and sugars?
Then they would disolve in water, and would be useless in conjunction with aqueous solutions.
What salt is the most acidic?
Ammonium salts of chloride, sulphate and nitrate in aqueous solutions are sufficiently acidic in nature.
Are detergents acid or base?
Solid detergents are neutral salts of long chain sulphonic acids but their aqueous solutions are basic in nature.
How do you do copper coating on iron powder?
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
What chemical system can Ksp be assigned?
Ksp or solubility product is meaured for aqueous solutions of salts, for acids is Ka , for bases is Kb and for water is Kw.
What are copper salts?
Copper salts are salts of copper as chlorides, sulfate, phosphate, nitrate, acetate etc.
Are ammonia and copper mixed together a chemical?
1. Ammonia (gas, NH3) and copper (solid, Cu) cannot be mixed. 2. Ammonia can react with copper salts in water solutions.
A substance is classified as an electrolyte because?
...its aqueous solution conducts an electric current This is because solutions of acids, bases, and salts are electrolytes and conduct electricity. AK
How can you make salts out of aqueous ammonia?
Salts are obtained after the reaction of NH4OH with acids.
Acids Bases Salts?
In water solutions salts may be acidic, basic or amphoteric.
