Silver, copper, and iron can turn dull when not in use due to a process called oxidation. Exposure to air and moisture causes a chemical reaction that forms a layer of oxide on the surface of the metal, which appears as a dull or tarnished coating. This can be removed through cleaning and polishing to restore the metal's shine.

What will happen if you put an iron nail in a copper sulfate solution?
When an iron nail is placed in a copper sulfate solution, a single displacement reaction occurs. The iron will displace the copper in the solution, forming iron sulfate and depositing copper on the nail, causing it to turn a brownish color due to the presence of copper.
What signs of a reaction are there between iron and copper oxide?
When iron reacts with copper(II) oxide, a redox reaction occurs. The iron reduces the copper(II) ions in the copper oxide, resulting in the formation of iron(II) oxide and elemental copper. The iron will appear to turn black as it reacts with the copper oxide, while the copper formed will have a reddish-brown color.
When copper sulphate reacts with iron what colour does it turn?
When copper sulphate reacts with iron, the solution turns blue due to the formation of copper ions in the solution. This is because copper is displaced from the copper sulfate and iron sulfate is formed, leading to the blue color of the solution.
What is the colour of copper metal after being placed in silver nitrate solution?
Copper metal will turn a silver color when placed in silver nitrate solution due to a displacement reaction where silver ions (Ag+) from the solution form solid silver metal on the surface of the copper.
What happens when a silver spoon is kept immersed in aqueous copper sulphate solution?
When a silver spoon is immersed in aqueous copper sulphate solution, a displacement reaction occurs. The silver spoon will react with the copper sulphate, displacing the copper ions and forming silver sulphate solution. Over time, the silver spoon will start to turn slightly reddish as a thin layer of copper is deposited on its surface.
Will iron oxide turn copper green?
No, iron oxide will not turn copper green. The green patina on copper is typically the result of oxidation due to exposure to air and moisture, which forms copper carbonate or copper chloride compounds. Iron oxide itself does not have this effect on copper.
What happens when you mix silver and water together?
After awhile the silver will turn into copper because silver is originated from copper
Can silver dime turn copper?
Nope.
What will happen if you put an iron nail in a copper sulfate solution?
When an iron nail is placed in a copper sulfate solution, a single displacement reaction occurs. The iron will displace the copper in the solution, forming iron sulfate and depositing copper on the nail, causing it to turn a brownish color due to the presence of copper.
What happens when iron nail are placed in copper sulphate solutions with word equation?
If iron nails are placed in a copper sulphate solution they turn green and rusted which means they become copper plated nails.I think the word equation is :iron + copper sulphate - copper + Iron sulphate.Iron displaces copper

When copper sulphate reacts with iron what colour does it turn?
When copper sulphate reacts with iron, the solution turns blue due to the formation of copper ions in the solution. This is because copper is displaced from the copper sulfate and iron sulfate is formed, leading to the blue color of the solution.
What is the colour of copper metal after being placed in silver nitrate solution?
Copper metal will turn a silver color when placed in silver nitrate solution due to a displacement reaction where silver ions (Ag+) from the solution form solid silver metal on the surface of the copper.
Copper plus silver nitrate?
When copper is added to silver nitrate, a single displacement reaction occurs. The copper will displace the silver in the compound, forming copper(II) nitrate and silver. The silver will precipitate out of solution as a solid.
What happens on placing iron nails in a beaker containing Copper Sulphate?
When iron nails are placed in a beaker containing copper sulfate, a displacement reaction occurs. The iron will react with the copper sulfate solution, causing the iron to lose electrons and form iron sulfate while the copper in the solution will deposit onto the iron nails. This will result in the iron nails appearing to turn a reddish-brown color as they become coated with copper.
Will silvertone jewelry turn your finger green?
Yes. Silver tone jewelry will turn your finger green because the metal under the silver tone is probably a brass which contains copper. It is the copper that turns your finger green.
What happens when a silver spoon is kept immersed in aqueous copper sulphate solution?
