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.

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.


Why colour of copper sulphate solution changes to light green when iron filings are added?

The color change occurs because the iron filings react with copper sulfate, forming iron sulfate and copper. This reaction results in a displacement reaction, where the iron displaces the copper in the compound. This changes the chemical composition of the solution, resulting in a light green color.


What change will happen when copper sulphate is heated?

It turns into blueish clear crystals but only if u don't have a lid on it when it is heated!add. as it is heated, the water of crystallization will be driven off, and soon you'll have a greenish powder.


When blue salt of copper sulphate is heated it becomes colourless why?

actually blue salt of copper sulphate is chemically copper sulphate penta hydrate( CuSO4.5H2O ). blue coloure is due to thiese 5 moles of water . by heating this water evaporates and leaving CuSO4 which is colourless


Does copper sulphate undergo any physical or chemical changes during heating?

When heated, copper sulfate undergoes a reversible physical change where it loses its water molecules (dehydration) and changes color from blue to white. This process is purely physical and does not involve any chemical reactions.

Why does the color of copper sulphate change when an iron nail is dipped in it?

When an iron nail is dipped in copper sulfate solution, a displacement reaction occurs. Iron is more reactive than copper, so it displaces copper in the solution and forms iron sulfate. This reaction causes the color change from blue (copper sulfate) to green (iron sulfate) as the copper ions are replaced by iron ions in the solution.


What colour does hydrous copper sulphate turn when heated?

Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.

What colour is anhydrous copper sulphate once heated?

Hydrated copper sulphate (CuSO4.5H2O) is BLUE Anhydrous copper sulphate (CuSO4) is white at any temperature.


Why is there no colour change when a silver rod is put in blue copper sulphate solution?

When a silver rod is placed in a blue copper sulphate solution, there is no visible color change because silver is less reactive than copper. This means that silver does not displace copper from copper sulfate solution during the reaction, so the blue color of the copper sulfate solution remains unchanged.


What happen when an iron nail is dipped in copper sulphate solution. why does the colour changes?

The iron is a more active metal than copper, so the iron atoms in the nail replace the copper atoms in the copper sulphate solution, so it becomes iron sulfate. The copper atoms will start to build on the iron nail, as well.
