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.
Why is graphite used as an electroed in dry cells?
Dry cell graphite electrode when treated with permanganate can be used as a hydrogen ion sensor. where activated dry cell graphite electrode seem to be suitable as potentiometric indicator electrodes. :)
. Scientists have chosen an arbitrary electrode to serve as a reference to determine the standard cell potential. Which electrode was chosen for this purpose copper electrode platinum electrode zinc e?
The platinum electrode is commonly chosen as a reference electrode for measuring standard cell potential. This is because platinum is inert, has excellent conductivity, and does not participate in redox reactions, making it a stable reference point. In electrochemistry, the standard hydrogen electrode (SHE), which uses a platinum surface, is often used as the universal reference electrode.
Why Carbon electrode are commonly Used in Electrolytic Cell?
Carbon electrodes are commonly used in electrolytic cells due to their excellent electrical conductivity, chemical stability, and resistance to corrosion. They can withstand the harsh conditions of electrolysis without degrading, making them suitable for various electrolyte solutions. Additionally, carbon's ability to be easily shaped into different forms allows for versatile electrode designs, enhancing the efficiency of the electrochemical processes.
What occurs when an electrolytic cell is used for silver-plating a spoon?
When an electrolytic cell is used for silver-plating a spoon, an electric current is passed through an electrolyte solution containing silver ions. The spoon serves as the cathode (negative electrode), attracting silver ions from the solution, which then reduce and deposit as metallic silver on its surface. Simultaneously, oxidation occurs at the anode, often involving a silver electrode that releases more silver ions into the solution. This process allows for a thin, even layer of silver to be plated onto the spoon.
Why does hydrogen gas liberate at Cu electrode in Zn-Cu cell?
In a zinc-copper cell, zinc gives up electrons, forming the negative terminal of the cell, and the electrons flows as electric current through wires. When the electrons reach the other positive terminal, electrolysis of the electrolyte takes place at the positive terminal. Hydrogen ions and the cation of the electrolyte will be attracted to the positive Copper electrode. The hydrogen ions, being less reactive than the cation ions, will take up the electrons on the copper electrode, forming hydrogen gas.
What is the name of liquid in batteries?
electrolyte When electrodes are placed in an electrolyte and a voltage is applied, the electrolyte will conduct electricity. In batteries, two metals with different electron affinities are used as electrodes; electrons flow from one electrode to the other outside of the battery, while inside the battery the circuit is closed by the electrolyte's ions. Here the electrode reactions convert chemical energy to electrical energy.
What is the energy conversion for dry cell?
A dry cell converts chemical energy into electrical energy. Inside the cell, a chemical reaction occurs between the electrolyte and the electrode materials, generating a flow of electrons. This flow of electrons creates an electric current that can be used to power devices. The efficiency and voltage output depend on the specific materials used in the dry cell.
What are the definition of electrodes?
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum).
What kind of material is used to make the positive electrode of a dry cell?
The positive electrode is a graphite rod (elemental carbon).
Difference between reference electrode and indicator electrode?
Often electrochemical studies are interested in one of the electrodes of the cell only. The second electrode is present to complete the cell. Electrode of interest is named working electrode or the indicator electrode; the second electrode is know as reference electrode or auxiliary electrode (counter electrode).
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 is the use of mercury in standard hydrogen electrode?
Mercury is used in the standard hydrogen electrode as a platform to host the hydrogen gas phase. It allows for the measurement of the standard hydrogen electrode potential by providing a stable interface for the hydrogen gas to interact with the surrounding electrolyte solution.
What impact did Michael Faraday to the world?
He created the technique and apparatus used for electrolysis. And he coined the terms anode, cathode, cation, anion, electrode and electrolyte. YOUR WELCOME!
