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.
Then they would disolve in water, and would be useless in conjunction with aqueous solutions.
Ksp or solubility product is meaured for aqueous solutions of salts, for acids is Ka , for bases is Kb and for water is Kw.
1. Ammonia (gas, NH3) and copper (solid, Cu) cannot be mixed. 2. Ammonia can react with copper salts in water solutions.
In water solutions salts may be acidic, basic or amphoteric.
There will be no reaction if all the reactants and possible products are aqueous while there is no insoluble salts precipitate that are formed.
Yes, the iron is used to displace copper from solutions of its salts. c';
Nitrates are salts and generally form stable solids, they are generally soluble and form aqueous solutions.
Then they would disolve in water, and would be useless in conjunction with aqueous solutions.
Ammonium salts of chloride, sulphate and nitrate in aqueous solutions are sufficiently acidic in nature.
Solid detergents are neutral salts of long chain sulphonic acids but their aqueous solutions are basic in nature.
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.
Ksp or solubility product is meaured for aqueous solutions of salts, for acids is Ka , for bases is Kb and for water is Kw.
Copper salts are salts of copper as chlorides, sulfate, phosphate, nitrate, acetate etc.
1. Ammonia (gas, NH3) and copper (solid, Cu) cannot be mixed. 2. Ammonia can react with copper salts in water solutions.
...its aqueous solution conducts an electric current This is because solutions of acids, bases, and salts are electrolytes and conduct electricity. AK
Salts are obtained after the reaction of NH4OH with acids.
In water solutions salts may be acidic, basic or amphoteric.
