What are electrodes?
Electrodes are electrical conductors used to connect a non-metallic part of a circuit to a metallic part, allowing electric current to flow between them. They are commonly used in batteries, electrochemical cells, sensors, and medical devices to facilitate the transfer of electrons.
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 apparatus is used for electrolysis of substances?
The apparatus used for electrolysis typically includes an electrolytic cell, which consists of two electrodes (an anode and a cathode) immersed in an electrolyte solution. A direct current power source is connected to the electrodes to drive the electrochemical reactions. Additional components may include a beaker or container to hold the electrolyte and a stirring device to ensure uniformity in the solution.
What types of electrodes are used?
1. M.M.O.(MIXED METAL OXIDE) 2. MAGNESIUM ANODE3. ALUMINIUM ANODE4. ZINC ANODE5. PURE IRON ANODE6. PENCIL ANODE7. H.S.C.I. ANODE(high silicon cast iron)8. Pb-Ag ANODE9. PLATINUM ANODE (Pt-Ti & Pt-Nb)
What is primary standard electrode?
A primary standard electrode is a reference electrode with a known and stable electrochemical potential that is used as a standard for calibrating other electrodes. These electrodes provide a precise and reproducible reference potential for accurate measurements in electrochemical experiments. Examples include the saturated calomel electrode (SCE) and the silver/silver chloride electrode.
What parts of the cell are used to connect a electrochemical cell to a circuit?
The nodes of the electrochemical cell are called the electrodes. The Cathode is the + end (of a battery). Negative charge enters through it. The - end is called the anode.
What is the common term for an electrochemical cell in which terminals are connected to electrodes immersed in a solution of electrolytes?
The common term for an electrochemical cell in which terminals are connected to electrodes immersed in a solution of electrolytes is a "battery." In a battery, chemical reactions at the electrodes produce an electric current that can be used to power devices.
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 Pt electrodes?
Pt electrodes refer to electrodes that are made of platinum. These electrodes are commonly used in various electrochemical applications due to platinum's inert nature, high conductivity, and stability in corrosive environments. Pt electrodes are versatile and can be used in different setups such as in fuel cells, sensors, and electrophysiology experiments.
What is the electrochemical cell used to power a flashlight?

What are electrodes?

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 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.

What are used in an electrochemical cell?
Two different metals and a conducting fluid.
What are used in electrochemical cell?
Two different metals and a conducting fluid.
What is the name of a chemical used between the electrodes in a cell or battery?
Electrolyte
What will be happen if you are using the same metal as anode and cathode?
If the same metal is used as both the anode and cathode in an electrochemical cell, no redox reaction will occur and no electrons will flow between the electrodes. This would result in no electricity being generated or no chemical reaction taking place within the cell.
