What are inert and active electrodes?
Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.
What are the metal strips called that are placed in the copper compound solution during electrolysis?
The metal strips are called electrodes. The positive electrode is known as the anode, and the negative electrode is called the cathode. They are used to conduct electricity through the electrolyte solution to facilitate the electrolysis process.
What can substitute copper or zinc electrode?
For copper, you can substitute with graphite electrodes which are commonly used in electrochemistry applications. For zinc, you can consider using magnesium electrodes as they are also commonly employed in electrochemical processes as a sacrificial anode. Always ensure compatibility with the specific electrolyte and application conditions.
What are the materials for How to make a potato battery?
To make a potato battery, you will need a potato, two different metal electrodes (such as zinc and copper), wire with alligator clips, and a small LED light. The potato serves as the electrolyte in the battery, while the metal electrodes act as the anode and cathode. Connect the electrodes with wires and clip an LED to show the flow of electricity.
Why in conductivity cell pt electrode is used instead of cu electrode?
Platinum electrodes are used in conductivity cells because they are inert, stable, and have a wide potential window, making them suitable for a wide range of electrolytes. Copper electrodes can be reactive in some electrolytes, leading to interference or contamination of the sample being measured.
What is the voltage of an electrolytic cell with nickel and copper electrodes?
-0.59 V
How many volts can a lime produce?
The voltage an electrochemical cell produces does not depend on the electrolyte (e.g. type of fruit), it depends on the two electrodes (e.g. metal strips). The voltage is determined by the relative electronegativities of the two electrodes. For example all cells using a copper electrode and a zinc electrode will produce the same voltage, regardless of the kind of electrolyte they are put into. Another example all cells using a carbon electrode and a zinc electrode produce 1.5 volts, regardless of whether the electrolyte is acidic (the original dry cell batteries), basic (modern alkaline batteries), or neutral (a salt).
What is the voltage of an electiolytic cell with nickel and copper electrodes?
The voltage of an electrolytic cell with nickel and copper electrodes depends on the specific electrolyte used and the concentration of the solutions. Typically, nickel and copper electrodes can have a cell potential of around 0.3 to 0.5 volts when considering their standard reduction potentials. However, in an electrolytic cell, an external voltage is applied to drive the non-spontaneous reactions, which may exceed this value. The actual voltage required will depend on factors such as electrode surface area, temperature, and the specific setup of the cell.
What gets oxidized in electrolytic cell made with nickel and copper electrodes?
Cu(s)
Does a cell with copper and zinc electrodes in an acid electrolyte produce voltages?
Yes, a cell with copper and zinc electrodes in an acid electrolyte will produce voltage because of the difference in their reduction potentials. The zinc will undergo oxidation at the anode, releasing electrons and creating a potential difference with the copper cathode where reduction occurs. This potential difference between the two electrodes generates an electric current.
How do you use electrode in a sentence?
Inez used a zinc nail and copper penny as electrodes in her science project.
What gets oxidized in an electrolytic cell made with nickel and copper electrodes?
Cu(s)
Why is copper used in the contruction of electrodes?
Copper is used in the construction of electrodes because it is a good conductor of electricity, corrosion resistant, and malleable. These properties make it ideal for carrying electrical current and withstanding the chemical reactions that occur during electrode processes.

Does copper need a voltage to produce a current?
Copper can not of itself produce a current. <><><><><> However, resistance, be it copper or some other material, will produce a current if a voltage is applied to it. The rule is Ohm's law: Current = Voltage divided by resistance.
Why does zinc and copper create a higher voltage than copper and copper in a circuit?
It is very weird and I am gonna help. Zinc and copper create a higher voltage than copper and copper because zinc has a higher voltage than copper so copper plus zinc equals more than copper plus copper.
What gets oxidized in a electrolytic cell made with Nickel and copper electrodes?
In an electrolytic cell with nickel and copper electrodes, nickel at the anode gets oxidized, losing electrons to form nickel ions. The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.
