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.
What electrolyte and electrode is used in weston cell?
1.Mercury cadmium amalgam -covered on its surface with a paste of cadmium sulphate crystals acts as the cathode.2.Pure mercury -covered with a paste of mercurous sulphate acts as the anode.3.Cadmium sulphate -acts as the electrolyte
Why is standard hydrogen electrode called reversible electrode?
Depending on the other cell used, it can turn H+ ions into hydrogen gas, or it can turn hydrogen gas into H+ ions. Thus it is reversible.
Can pencil lead be used as an electrode?
Pencil "lead" is actually a mixture of graphite and clay, and is not an ideal choice for an electrode due to its impurities and inconsistent conductivity. It is better to use pure graphite or metal electrodes for more accurate and reliable results in electrochemical experiments.
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).
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 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.

What is open circuit potential which is used to determine corrosion of materials?
The open circuit (oc) potential is the potential of the working electrode relative to the reference electrode when no potential or current is being applied to the cell.
Why is standard hydrogen electrode called reversible electrode?
Depending on the other cell used, it can turn H+ ions into hydrogen gas, or it can turn hydrogen gas into H+ ions. Thus it is reversible.
