Galvanic cells, also known as voltaic cells, are electrochemical cells that convert chemical energy into electrical energy through spontaneous redox reactions. They consist of two half-cells connected by a salt bridge, with electrons flowing from the anode to the cathode, generating an electric current.

Electrochemical cells are devices that convert chemical energy into electrical energy through redox reactions, consisting of two half-cells connected by a salt bridge or porous membrane. They are fundamental in powering batteries and are essential for various applications, from portable electronics to industrial processes.

electrochemical cells

Chemical energy is a form of potential energy stored in the bonds of chemical compounds, which is released or absorbed during a chemical reaction. It plays a crucial role in biological processes, industrial applications, and energy generation, influencing both natural and engineered systems.

chemical energy

Electrical energy is the energy derived from electric potential energy or kinetic energy, associated with the movement of electric charges. It is a versatile form of energy that can be easily converted into other forms such as light, heat, or mechanical energy, making it essential for modern technology and daily life.

A salt bridge is a crucial component in electrochemical cells that maintains electrical neutrality by allowing the flow of ions between the two half-cells. It prevents the solutions from mixing while enabling the transfer of charge, thus sustaining the cell's ability to generate electricity continuously.

Electrons are subatomic particles with a negative electric charge, fundamental to the structure of atoms and the flow of electricity. They play a crucial role in chemical bonding and are key to understanding quantum mechanics and electromagnetic interactions.

electrons

The anode is the electrode where oxidation occurs in an electrochemical cell, and it is crucial for the flow of electrons in the circuit. In galvanic cells, it is the negative terminal, while in electrolytic cells, it is the positive terminal, demonstrating its role in different types of electrochemical reactions.

anode

A cathode is the electrode through which electric current flows out of a polarized electrical device. In electrochemical cells, it is the site of reduction reactions, attracting cations or positive charges from the electrolyte.

cathode

Electric current is the flow of electric charge through a conductor, typically measured in amperes. It is a fundamental aspect of electricity, enabling the operation of electrical devices and the transmission of power across distances.
