I dry it with acetone right on the vacuum filter after its been washed. This removes the water and the acetone can be then removed by gentle warming. But depending on your particle sizes you may need the inert atmosphere for it (Nitrogen, Argon) as the fine one can be pyrophoric in air.
Copper powder can be made by reducing copper oxide or copper hydroxide in a chemical reaction using a reducing agent such as hydrogen gas or carbon monoxide. This process typically involves heating the copper oxide or copper hydroxide with the reducing agent to yield copper powder.

How do you separate copper powder and salt?
One way to separate copper powder and salt is through a process called filtration. You can mix the salt and copper powder with water to dissolve the salt, leaving the copper powder behind. Then, you can use a filter to separate the solid copper powder from the liquid salt solution.
What is observed when air is passed over heated copper powder?
When air is passed over heated copper powder, the copper powder will react with the oxygen in the air, leading to the formation of copper oxide. This reaction can result in a color change in the copper powder from its original metallic color to a reddish-brown color.
How do you do copper coating on iron powder?
To copper coat iron powder, you can use electroless plating techniques where a reducing agent is used to deposit a layer of copper onto the iron powder. Another method is to mix the iron powder with a copper salt solution, followed by reducing the copper ions to form a copper coating on the iron particles.
Is copper powder behaves like iron powder when it mixed with sulfur?
When copper powder is mixed with sulfur, it does not react in the same way as iron powder does. Copper and sulfur do not have a strong affinity for each other, so they typically do not react vigorously like iron and sulfur do, which form iron sulfide. Copper sulfide is a more stable compound that can be formed under specific conditions.
How do you separate copper strips from sulfur powder?
To separate copper strips from sulfur powder, you can use a process called filtration. Mix the copper strips and sulfur powder with water to form a mixture. Then, pass the mixture through a filter paper to separate the solid copper strips from the sulfur powder, which will remain in the filter paper.
Why the colour of heated copper powder becomes black when air is passed over it?
When air is passed over heated copper powder, the copper undergoes oxidation, forming copper oxide. Copper oxide is black in color, which is why the heated copper powder appears black when air is passed over it.
What is the black powder formed on copper powder in an experiment?
The black powder formed on copper powder in an experiment is likely copper oxide. When copper is exposed to air, it can react with oxygen to form copper oxide, which appears as a black powder. This is a common reaction observed with metals that are prone to oxidation.
How do you separate copper powder and salt?
One way to separate copper powder and salt is through a process called filtration. You can mix the salt and copper powder with water to dissolve the salt, leaving the copper powder behind. Then, you can use a filter to separate the solid copper powder from the liquid salt solution.
Why does copper make a good gun powder holder?
Copper's malleability and ductility make it easy to shape into containers for gunpowder. It is also non-reactive with gunpowder components, providing a safe storage option. Additionally, copper's thermal conductivity helps dissipate heat, which can be important when handling explosive materials.
Why is iron powder magnetic?
Iron is magnetic but copper isn't. So I guess iron powder is magnetic while copper powder isn't.:)
Is copper oxide a black solid?
Cu2O (Copper(II) Oxide) is a Red Powder. CuO (Copper(I) Oxide) is a Black Powder.
What is observed when air is passed over heated copper powder?
When air is passed over heated copper powder, the copper powder will react with the oxygen in the air, leading to the formation of copper oxide. This reaction can result in a color change in the copper powder from its original metallic color to a reddish-brown color.

Another method is to mix the iron powder with a copper salt solution, followed by reducing the copper ions to form a copper coating on the iron particles.
What is the result after heating copper wire and sulfur powder?
Heating copper wire and sulfur powder together will result in the formation of copper sulfide. Copper sulfide is a compound where copper and sulfur atoms are chemically bonded together.
When you heat copper oxide and magnesium why do you get grey powder?
When you heat copper oxide and magnesium, a chemical reaction occurs where magnesium reduces copper oxide to produce copper metal and magnesium oxide. The grey powder formed is likely a mixture of copper and magnesium oxide.
Is the solid left behind after a copper and sulfermixture is heatedf is it a compound or a element?
Copper powder reacts with molten sulphur to make copper(I) sulphide (a compound). 2Cu + S -> Cu2S Please see the link.
What do copper sulfate baking powder and nickel have in common?
Okay, let's take the basics: There is no such thing as "copper sulfate baking powder", as it would be poisonous. I can think of no way to relate elemental nickel to the fictitious "copper sulfate baking powder".
