What else can I help you with?
If copper and zinc sulfate are all non black colors why do I get a black substance when copper sulfate reacts with zinc?
The zinc is either contaminated with copper, or the copper is depositing so quickly onto the zinc that it is in a non crystalline structure and therefore appears to be black. Try melting some of the black stuff with a blowtorch and see what happens.
Why does your copper wiring turn black?
Copper wiring can turn black due to oxidation, which occurs when the copper comes into contact with air and moisture. This chemical reaction forms a layer of copper oxide on the surface of the wire, giving it a black appearance. It is a natural process and does not affect the conductivity or performance of the wiring.
What does copper oxide look like after copper has burned?
Copper oxide appears as a black or dark brown powder after copper has burned.
Is copper sulfate black?
Copper sulfate is not black. Combined with water, as hydrated copper sulfate, it is blue. Without water, as anhydrous copper sulfate, it is white.
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 black substance form when copper reacts with oxygen?
Copper oxide, a black substance, forms when copper reacts with oxygen in the presence of air.
What is the name of the black substance formed on copper?
The black substance formed on copper is called copper oxide. It is a chemical compound that forms when copper is exposed to oxygen in the air, resulting in a black or greenish-black tarnish on the surface of the copper.
Why is the black stuff on heated copper not soot?
The black substance that forms on heated copper is not soot because copper does not undergo combustion in the same way as carbon-based materials. The black substance is most likely copper oxide, formed when the copper reacts with oxygen in the air.
What type of substance is black copper oxide powder alkali or base?
Black copper oxide powder is a base because it can react with acids to form salts and water.
If copper and zinc sulfate are all non black colors why do I get a black substance when copper sulfate reacts with zinc?
The zinc is either contaminated with copper, or the copper is depositing so quickly onto the zinc that it is in a non crystalline structure and therefore appears to be black. Try melting some of the black stuff with a blowtorch and see what happens.
What causes copper cable turn black?
Copper cables can turn black due to oxidation, which is a natural process that occurs when copper is exposed to air and moisture. This leads to the formation of copper oxide on the surface, giving it a black color. Additionally, exposure to sulfur compounds in the environment can also contribute to the blackening of copper cables.
Why does your copper wiring turn black?
Copper wiring can turn black due to oxidation, which occurs when the copper comes into contact with air and moisture. This chemical reaction forms a layer of copper oxide on the surface of the wire, giving it a black appearance. It is a natural process and does not affect the conductivity or performance of the wiring.
By heating green copper carbonate so that it changes to black copper oxide will this be a chamical or physical change?
The change from green copper carbonate to black copper oxide is a chemical change because it involves a chemical reaction where the chemical composition of the substance is altered. The color change indicates a new substance has formed, making it a chemical change.
What causes brake fluid to turn black?
the biggest thing that causes brake fluid to turn "black" is high copper content. This is the result of your brake line deteriorating from the inside. when it is black you really should change it. the copper will start wearing out your rubber seals in your brake system, eventually resulting in............................. NO brakes!!!!
What colour is copper oxide and why?
Copper oxide is typically black or dark brown in color. This coloration is due to the presence of oxygen, which causes copper to oxidize and form the copper oxide compound. The specific shade may vary depending on the specific oxidation state of the copper ions in the compound.
What causes black-brown substance in the mouth?
My daughter is 9 years old, she woke up this moring with a black/brown substance on her teeth and tongue with a vomit tast in her mouth. what can cause this?
What is the result of combining copper and sulfur?
When copper and sulfur are combined, they form copper sulfide, which is a dark grey or black compound. This chemical reaction is often used in educational demonstrations to showcase the formation of a new substance through a chemical change.
