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. :)
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.
What is the difference between a dry cell and a voltaic cell?
A dry cell is a type of voltaic cell that uses a paste electrolyte, such as manganese dioxide, instead of a liquid electrolyte. Voltaic cells, on the other hand, can have different types of electrolytes, including liquid solutions. Dry cells are commonly used in batteries for everyday devices, while voltaic cells are used in various industrial applications and laboratories.
What factors affect the cell capacity of a battery?
Several physical factors affect the capacity, including the quantity of active materials; the number, design, and the dimensions of the plates; and the electrolyte concentration. Operational factors affecting capacity include discharge rate, charging method, temperature, age, and conditions of the cell or battery.
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 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 name of a chemical used between the electrodes in a cell or battery?
Electrolyte
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!
Can solid sodium chloride be used as an electrolyte in a cell?
Only in solution or melted.
What happens when sodium ions come in contact with the negative electrode in a cell used for electrolysis?
When sodium ions come in contact with the negative electrode in a cell used for electrolysis, they accept electrons and get reduced to form sodium metal. This process occurs as part of the overall electrolysis reaction, where positive ions are reduced at the negative electrode while negative ions are oxidized at the positive electrode.
