Electrochemical potential is the energy required to move a mole of charged particles from one point to another in a system, factoring in both chemical potential and electrical potential. It is a fundamental concept in understanding how ions and electrons are transported in electrochemical cells, affecting processes like battery operation and nerve impulse transmission.

Chemical potential is a measure of the change in a system's energy when an additional particle is introduced, keeping temperature and volume constant, and it plays a crucial role in determining the direction of chemical reactions and phase transitions. It is a fundamental concept in thermodynamics and statistical mechanics, providing insight into how substances distribute themselves in different phases and react chemically.

Electrical potential is the amount of work needed to move a unit charge from a reference point to a specific point inside the field without producing any acceleration. It is a scalar quantity and is measured in volts, reflecting the potential energy per unit charge in an electric field.

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.

Nerve impulse transmission is the process by which neurons communicate with each other through electrical and chemical signals. This involves the generation of an action potential, its propagation along the axon, and the release of neurotransmitters at the synapse to relay the signal to the next neuron.
