Copper vessels lose their luster when exposed to air due to a process called oxidation. Oxygen in the air reacts with the copper to form copper oxide, giving the surface a dull appearance. This can be reversed by cleaning the copper with a mixture of vinegar and salt, or by using a commercial copper cleaner to restore its shine.

Is stainless steel lustrous?

Stainless steel is an alloy of iron, chromium, carbon and nickel. It never rust and hence,maintains its lustre. Whereas, the iron exposed in moist air rusts. It is covered with reddish substance and loses its lustre. And hence stainless steel has more lustre than iron.


What happens if Copper Sulphate penta-hydrate is heated?

When copper sulfate pentahydrate is heated, it undergoes a dehydration reaction where the water molecules are released, leaving behind anhydrous copper sulfate. This process is reversible, and when anhydrous copper sulfate is exposed to moisture, it will reabsorb water and form copper sulfate pentahydrate again.


What are the two forms of copper and what are the elements that form them?

The two forms of copper are copper(I) and copper(II). Copper(I) is formed when copper loses one electron, while copper(II) is formed when copper loses two electrons. Copper(I) is typically bonded with elements such as chlorine or iodine, while copper(II) is commonly bonded with elements like oxygen or sulfur.

Are Ions copper?

Yes, copper ions are ions of the element copper. They are positively charged particles formed when a neutral copper atom loses one or more electrons.


When you heat copper sulphate with Bunsen burner?

Heating copper sulfate with a Bunsen burner will cause the compound to undergo a dehydration reaction, where it loses water molecules to form anhydrous copper sulfate. The characteristic blue color of the copper sulfate will change as it loses water molecules and turns white.


What is the chemical formula for copper ll?

The chemical formula for copper (II) is Cu^2+. When copper loses 2 electrons, it forms a 2+ cation.


How does the amount of surface exposed to air affect how fast a leaf loses water?

The more surface area exposed to air, the faster a leaf loses water through evaporation. This is because a higher surface area allows for more water to evaporate into the surrounding air.


Did the color of Copper ( ) sulfate change?

Yes, the color of copper sulfate changes from blue to white when it loses water molecules and turns into anhydrous copper sulfate.


What is curie temperature of copper sulphide?

The Curie temperature of copper sulfide is approximately 32Β°C, above which it loses its ferromagnetic properties.


What are examples of efflorescent substances?

Efflorescence refers to the process where wet particles decrease in size through losing water to eventually crystallize out. An example of an efflorescent substance is the common Copper(II) sulfate crystal (CuSO4.5H2O), a blue crystalline solid that when exposed to air, slowly loses water of crystallization from its surface to crystallise to form a white layer of anhydrous copper(II) sulfate.
