Copper vessels tarnish by reacting with oxygen in the air (black copper oxide is formed) or by reacting with water (green copper hydroxide is formed, commonly known as VERDIGRIS ; pronounced ver-dee-gree).
These substances coat the metal and can be very difficult to remove as they often sit in small depressions in the surface of the metal and they aren't very soluble in water
Lemon juice contains citric acid. This reacts with the copper oxide and copper hydroxide to produce copper citrate. This is readily soluble in water and washes off easily, leaving the sparkling and unadulterated shiny copper surface.

Why does a copper vessel turn green in color in the rainy season?
Oh, dude, that's just some good ol' science at work! So, like, when copper reacts with oxygen and moisture in the air, it forms copper oxide, which is that greenish layer you see. It's like the copper's way of saying, "Hey, I'm chillin' here, just oxidizing and turning green, nbd." So, yeah, the rainy season just gives it the perfect conditions to show off its new look.
Can you store copper chloride in an iron vessel?
Emphatically no! Iron or steel will rapidly dissolve in hydrochloric acid generating hydrogen gas. Even stainless steel is not very good for containing hydrochloric acid. Chloride ions are highly corrosive and cause normal grades of stainless to pit and crack. The best bet (besides avoiding it altogether) is glass (as it is stored in a laboratory) or plastic - PVC, polyethylene, or polypropylene.
Why it is not advisable to keep food in copper vessel?
A reaction occurs and copper metal may get corroded due to the humidity or moistness from the food. When corroded due to the oxides and moistness , copper may make the food toxic. So, it is advised not to store food in copper vessels. Additional note: Aluminium kind of has the same effect. So, do not store food in aluminium vessels either.
Seam to seam length in horizental vessel?
The seam to seam length in a horizontal vessel refers to the distance measured from one seam to the opposite seam of the vessel along its circumference. It is an important measurement for determining the size and capacity of the vessel. This measurement is typically used in the fabrication and design of horizontal vessels such as tanks or pressure vessels.
A vessel with an internal volume of 10.0L contains 2.80g of nitrogen gas 0.403g of hydrogen gas and 79.9g of argon gas At 25 degrees C what is the pressure in ATM inside the vessel show work?
To find the pressure inside the vessel, first calculate the number of moles of each gas using the ideal gas law equation PV = nRT. Then, add up the total moles of gas in the vessel. Next, use the mole fraction of each gas to determine the partial pressure of each gas. Finally, sum the partial pressures to get the total pressure in the vessel.
Why tarnished copper vessels are cleaned with lemon or tamarind?
Copper oxide is basic in nature.Lemon or tamarind is acidic.Hence, when we rub tarnished copper vessel with lemon juice or tamarind, the basic copper oxide reacts with acid(citric acid) present in the lemon or tamarind to form a salt which is washed away with water.Hence,the vessel gets cleaned.
What happen when copper sulphate is stored in iron vessel?
Since iron is a more active metal than copper, the iron would replace the copper in the copper sulfate, forming iron sulfate, and releasing elemental copper. The copper will not shape itself into a copper vessel, so eventually, the iron sulfate would leak out of the iron vessel, and eventually, if there is enough copper sulfate, the iron vessel will cease to exist.
What happens when black uranium is added to copper vessel?
Uranium doesn't react with copper.
Can we store copper sulphate solution in a silver vessel?
It is not recommended to store copper sulfate solution in a silver vessel as silver can react with copper sulfate to form silver sulfate and copper, leading to contamination of the solution. It is better to store copper sulfate solution in a glass or plastic container.
When a vessel is exposed to air for a long time then a green coating is formed by which element this vessel is made up of?
the vessel is made up of copper
Why is a copper vessel covered with a green coating in rainy season?
The green coating on a copper vessel in the rainy season is due to the formation of copper carbonate (patina) when copper reacts with moisture and carbon dioxide in the air. This patina acts as a protective layer, preventing further corrosion of the copper surface.
Why is a copper vessel covered with 'green'coating in rainy season?
The green coating on a copper vessel in the rainy season is due to a process called oxidation. When copper reacts with moisture and carbon dioxide in the air, it forms a layer of greenish copper carbonate on its surface. This layer, called patina, protects the copper underneath from further corrosion.
Can you store copper sulphate solution in silver vessel but not in aluminium vessel?
It is not possible to store copper sulphate solution in iron vessel.since ,iron is more reactive than copper,it displaces copper from any if its solution.the reaction takes place as , Fe(s)+CuSo4(aq)..............>FeSo4(aq)+Cu(s) (Blue color(light green solution)solution)
Why is copper vessel is covered with the green coating in rainy season?
This is copper's version of oxidisation. It occurs very visibly on buildings with copper trim on the roofs.
Where can one find Copper Vessel Sinks?
Copper Vessel sinks can be found at home renovation stores such as Lowes or Home Depot. Vessel sinks are very large bathroom sinks. They are also available in stainless steel or ceramic. A plumber would be able to install it.
Where could a person buy a copper vessel sink?
copper vessel sinks can be purchased from any good and reputable kitchen and bathroom specialists also you may find them in certain mega stores and hardware suppliers
What is the use of a copper bird bath?
A copper bird bath is a copper vessel that holds water for birds to bathe in. One advantage of a copper bird bath over an iron bird bath is that copper does not rust.
