Why can iron be used to get copper sulfate solution?
Because iron is a more reactive metal than copper.
How are magnets used in junk yards?
Rather than "permanent" magnets, the large electromagnets used in junkyards only create a magnetic field when electric current flows through them. They are used to lift iron and steel scrap, and to separate it from non-magnetic scrap. The cranes have an electric generator connected to a wire coil in the large round lifting disc. When the power is on, its magnetic field attracts heavy iron and steel to it. When the scrap is positioned where they want it, they cut the power to the electromagnet and the scrap drops. They are attached to cranes and are used to lift up heaps of scrap metal
What element used to be mined in Michigan?
Primarily copper and iron.
Is iron or copper stronger?
Even in its pure form, iron is stronger than copper (although copper doesn't rust the way iron does) and iron is also used in making various kinds of steel which are much stronger than iron, and incomparably stronger than copper. Copper can also be used in alloys which are stronger than pure copper, such as brass and bronze, however, even the strongest copper alloy is much weaker than steel. Copper is much more electrically conductive than steel, and along with its greater flexibility and resistance to chemical corrosion, this makes it much better for wiring than iron or any iron alloy would be. So for each metal, there are particular uses. . Bronze (an alloy of mostly copper with up to 23% tin) is a much stronger metal than iron. This is why during the early iron age, the Roman foot soldiers were issued iron swords but their commanders had bronze swords.
The blue colour of the solution fades during the electrolysis of copper sulfate. Explain why.?
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
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';
Why is it economical to use scrap iron to get copper?
By using scrap iron, you are not using iron which can be used elsewhere, like in buildings. It also saves money on sourcing and extracting new iron.
How scrap iron is used to displace copper from solution?
In general, any metal higher than copper in the "electromotive series" will displace copper from copper sulfate solution. This category includes all the alkali and alkaline earth metals and other common metals such as iron and zinc. For example Aluminum and Iron both displace Copper: Aluminum in Copper sulfate will trade places in the ionic balance of the solution and 'join' with the sulfate. CuSO4(aq) + Al(s) ==> AlSO4(aq) + Cu++(s) Because this single displacement reaction occurs in immediate proximity to the aluminum, Copper++ ions accumulate in a fluffy rust colored fur around the aluminum. Iron in Copper Sulfate will also go into the aqueous sulfate solution and the Copper will precipitate onto the Iron CuSO4(aq) + Fe(s) ==> FeSO4(aq) + Cu?(s) This reaction happens at the ferrous surface more intimately than the Aluminum and the Copper is deposited as a 'plate'.
Why will iron displace copper from aqueous solutions of copper salts?
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.
Why copper is not used to prepare hydrogen in the laboratory?
copper doesn't displace hydrogen from acids
What magnet is used for scrap heap magnet?
They are used everyday to move scrap iron around the scrap yard...
Why can iron be used used to get copper from copper sulfate solution?
Iron is more reactive than copper
What is an everyday use for scrap heap magnets?
They are used everyday to move scrap iron around the scrap yard...
Why can iron be used to get copper from copper sulfate solution?
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).
How does scrap iron scarecrow work?
scrap iron scarecrow can only be used once per turn and can't stop initiative attacks
Can copper be used to prepare hydrogen by reaction with diluteacids?
No. Copper is below hydrogen in the electromotive series and therefore can not displace hydrogen from its compounds.
