. 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 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 is the unit of cell constant?
The unit of cell constant is reciprocal centimeters (cm^-1). It is a measure of conductivity in conductivity cells used for measuring the electrical conductivity of a solution.
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 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 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.

Why KCl is used as the standard for verification of cell constant?
a verification code is used to validate that a system complies with the requirements
What is a reference electrode?
A reference electrode is a stable electrochemical electrode with a known and constant electrode potential. It is used as a comparison point in electrochemical measurements to determine the potential of another electrode in a cell. Reference electrodes help provide accurate and reliable measurements in various electrochemical processes.
