What type of metal should be in the electrolyte solution?
metal nitrate
The negative electrode should be the object to be electroplated. The positive electrode should be the metal that you want to coat the object with. The electrolyte should be a solution of the coating metal, such as its metal nitrate or sulfate.
Why is it important for the solution that the electrodes are placed in contain the same metal as the electrode?
The solutions have to have the complementary ion to their respective metal. Galvanic cells work because when electrons flow from metal to solution or vice-versa, the metal atoms that they were bound to must flow with them.
Do electrodes have to be metal?
Electrodes are typically good electric conductors, but they need not be metals. In an electrochemical cell, reduction and oxidation reactions take place at the electrodes. Oxidation takes place at the anode. Whether an electrode operates as a cathode or anode depends on the direction the cell is operating in.
Which metal salt solution is electrolyte?
Salt solution of Metal ( CuSO4 ) is taken as electrolyte.
What electrode are metal ions attracted to?
positive metal ions are attracted to the negative electrode, where they gain electrons and form metal atoms.
What needs to be placed between the metals to make a cell?
A simple cell can be made by connecting two different metals in contact with an electrolyte. A number of cells can be connected in series to make a battery , which has a higher voltage than a single cell. In non-rechargeable cells, eg alkaline cells, a voltage is produced until one of the reactants is used up.
What are electrodes and electrolytes?
Electrolyte and electrode are two very important concepts discussed in the fields of electrochemistry. An electrolyte is basically a solution of ions. An electrode is a device that is used to create an electrical connection between a conductor and a non-conductor.
Are all electrodes made of metals?
Electrodes often are made of metal. Sometimes they are graphite. But whatever they’re made of, electrodes must be conductors. These electrodes are key parts of what scientists call an electrochemical cell.
How do you choose electrolytes for electroplating?
When choosing the type of electrolyte some things to keep in mind are corrosion, resistance, brightness or reflectivity, hardness, mechanical strength, ductility, and wear resistance.
