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 do not chemically react during the electrochemical process and are typically made of materials like platinum or graphite. Active electrodes participate in the chemical reactions of the electrochemical process and can be consumed or altered during the reaction. Examples of active electrodes include metals like copper or zinc.
What types of electrodes are used?
Common types of electrodes include metal electrodes, such as copper, zinc, and aluminum, as well as carbon electrodes like graphite. Other specialized electrodes like platinum and gold electrodes are also used for specific applications. Additionally, reference electrodes like Ag/AgCl electrodes are commonly used in electrochemical measurements.
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 is the difference between a galvanic cell and a voltaic cell?
There is no difference between a galvanic cell and a voltaic cell - they are two terms that refer to the same type of electrochemical cell that converts chemical energy into electrical energy. Both terms are commonly used interchangeably in the field of chemistry.
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?

Difference between reference electrode and indicator electrode?
A reference electrode is used to establish a stable electrochemical potential for comparison within a measurement system, while an indicator electrode is used to respond to changes in the analyte concentration being measured. Reference electrodes provide a fixed potential, whereas indicator electrodes change their potential in response to the analyte's concentration.
What are inert and active electrodes?
Inert electrodes do not chemically react during the electrochemical process and are typically made of materials like platinum or graphite. Active electrodes participate in the chemical reactions of the electrochemical process and can be consumed or altered during the reaction. Examples of active electrodes include metals like copper or zinc.
What are used in electrochemical cell?
Two different metals and a conducting fluid.
What are used in an electrochemical cell?
Two different metals and a conducting fluid.
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.
What is the name of a chemical used between the electrodes in a cell or battery?
Electrolyte
