What else can I help you with?
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 does the color of copper sulphate change when an iron nail 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.
Iron nail dipped in copper sulphate solution?
When an iron nail is dipped in the solution of copper sulphate solution , after a while the solution changes into the colour of green becoming iron sulphate and a brown substance is found on the iron nail which is copper so we get to know that the displacement reaction is produced
When zinc metal is placed into a solution of copper sulphate a pinky brown metal is formed but when a piece of silver metal is placed into another solution of copper sulphate no change is observed Why?
Silver is lower in the reactivity series than Zinc and therfore cannot displace the Sulphate from the Zinc. But on the other hand zinc is higher than copper, and when displacing the sulphate from the copper it changes colour due to the reaction. Reactivity series(metals): Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Silver Gold Platinum
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 do you use copper sulphate?
A rather incomplete question. I could use copper sulphate for a number of reasons, for example as an electrolyte for copper plating, as a medium for growing impressive deep blue crystals, as a fungicide and so on. For fun, try dropping some iron filings into a fairly concentrated solution of copper sulphate and observe how the iron filings change to a copper colour and the solution changes to a green colour.
What is the colour of the solution if zinc is added to copper sulphate solution?
No colour
What is the colour of sodium sulphate solution by chemists?
The solution is colorless.
What is the colour of aqueous solution of ferrous sulphate?
The aqueous solution of ferrous sulphate is typically pale green in color.
What two colour changes do you get when you add copper sulphate solution to iron wool?
When you add copper sulphate solution to iron wool. The iron wool turns copper in color and the copper sulphate solution turns pale blue as the iron displaces the copper from the copper sulphate solution forming iron sulfate.
What color is copper sulphate solution and water mixture?
Copper sulphate's colour is blue.
When an iron nail is dipped into copper sulphate solution after sometime the colour is changed into?
When a iron nail is dipped into copper sulphate solution after sometime the colour is changed into pale green.
What is the color of ferrous sulphate solution?
The color of ferrous sulphate solution is pale green or light green.
Which ion is responsible for the colour that has observed in the copper2 solution?
sulphate
How benedict solution prepared?
A Benedict's solution is a solution of sodium citrate, sodium carbonate and copper sulphate, whose colour changes from blue to yellow to red in the presence of reducing sugars such as glucose.
What is the colour of ferric sulphate solution?
Ferric sulphate solution is typically yellow in color, often ranging from pale yellow to dark amber depending on its concentration.
What changes in the colour of iron nails and coppper sulphate solution do you observe after keeping the iron nails in copper sulphate solution for about half an hour?
After keeping iron nails in a copper sulfate solution for about half an hour, you will observe that the color of the iron nails changes to a reddish-brown due to the deposition of copper on the surface of the nails. The blue color of the copper sulfate solution will fade as copper is transferred from the solution to the nails.
