Leave the circuit running for 20-30 minutes, or until you are happy with the amount of copper on the key.

An electrical circuit has now formed with the positive electrodes & negative electrodes and an electrical current is flowing. The copper strip will produce a path for conductivity. The plating solution level is now below the alligator clip.

Place the copper strip/mass of copper into the solution, making sure it doesn't touch the key.

The alligator clip should not touch the solution.

Partially suspend the key in the solution by wrapping the wire lead loosely around a pencil and place the pencil across the mouth of the beaker.

Use one alligator clip and attach the copper electrode to the positive terminal of the battery (this is now the anode) and then attach the key to the negative terminal (now called the cathode).

Stir copper sulfate into some hot water in a beaker until no more will dissolve.

Prepare the key for the DIY copper plating by cleaning it with a thin layer of toothpaste or soap and water.Copper electrode (or coil of copper wire).Beaker or glass (250-ml beaker is recommended or similar glass size).Two alligator clip leads or insulated wire.1.5-volt D battery with the battery holder (for power supply).Watch us use electricity to copper-plate a brass key (copper electroplating) in this Home Science Tools video. (Adult supervision and chemical safety equipment required.) In copper electroplating, a metal substrate is placed in an electrolytic bath and an electric current is used to cause copper ions to adhere to the base material's surface.

Professional electroplating requires specialized chemicals and equipment to make a high-quality coat, but in this project, you can try your hand at a simple procedure that will transfer copper (a versatile, naturally occurring metal) to a brass key.īeing red in color, copper is known for its high electrical conductivity, malleability, and corrosion resistance. Jewelry and silverware can be silver- or gold-plated, while zinc is often used to coat iron to protect against corrosion. There are also specific types of electroplating such as copper plating, silver plating, and chromium plating. Using electricity, you can coat the metal of one electrode with the metal of the other in an electroplating process, also known as electrochemistry.Įlectroplating, also known as electrodeposition, is essentially a chemical reaction that helps to make various items we see and use every day. Chemical composition for HUARO Copper CathodeĪs one of the copper cathode suppliers specialized in this field, HUARUO will promise superior copper cathode and quality service.Electroplating uses a form of electrolysis in which the electrodes play a bigger role than just conducting the current. It is used for winding various cables, wires, motors, transformers, switches, printed circuit boards and other machinery and field. Application of Copper CathodesĬopper cathode is an non-ferrous metal which is closely related to human beings.Its widely used in electric, light industry, machinery manufacturing, construction, national defense industry and other fields.Ĭopper cathode is widely used in electronic industry, accounting for more than half of the total consumption. Impurities such as gold and silver, which are less active than copper, are deposited at the bottom of the cell The copper plate produced in this way, called 'Copper Cathode' or 'Electrolytic Copper Cathode', is of high quality and can be used to make electrical products. Because these ions are not easy to precipitate compared with copper ions, they can be avoided to precipitate on the cathode as long as the potential difference is adjusted properly. Impurities such as iron and zinc, which are more active than copper, will dissolve into ions (Zn and Fe) with copper. After being electrified, copper dissolves into copper ions (Cu) from the anode and moves to the cathode, where electrons are obtained and pure copper is precipitated. The thick plate made of crude copper (including 99%) is used as anode, the thin plate made of pure copper is used as cathode, and the mixture of sulfuric acid and copper sulfate is used as electrolyte. In terms of national distribution, the world's copper resources are mainly concentrated in Chile, the United States, Zambia, the Commonwealth of Independent States and Peru.

Copper in nature mainly exists in the form of compounds, namely copper minerals, which are mainly distributed in North America, Latin America and Central Africa. The content of copper in the crust is about 0.01%, and in some copper deposits it can reach 3% - 5%.
