  • Potential Determining Ion — In a colloidal dispersed system, ion dissolution arises, where the dispersed particles exist in equilibrium with their saturated counter part, i.e. mathrm{NaCl} {(s)} leftrightarrow mathrm{Na} {(aq)}^+ + mathrm{Cl} {(aq)}^ The behavior of this… …   Wikipedia

  • Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… …   Wikipedia

  • Metal ions in aqueous solution — A metal ion in aqueous solution is a cation, dissolved in water, of chemical formula [M(H2O)n]z+. The solvation number, n, determined by a variety of experimental methods is 4 for Li+ and Be2+ and 6 for elements in rows 3 and 4 of the periodic… …   Wikipedia

  • End-plate potential — Miniature end plate potentials and end plate spikes recorded from muscle fiber End plate potentials (EPPs) (sometimes called end plate spikes ) are the depolarizations of skeletal muscle fibers caused by neurotransmitters binding to the… …   Wikipedia

  • Reduction potential — (also known as redox potential, oxidation / reduction potential, ORP or Eh) is a measure of the tendency of a chemical species to acquire electrons and thereby be reduced. Reduction potential is measured in volts (V), or millivolts (mV). Each… …   Wikipedia

  • Point of zero charge — The point of zero charge (pzc), in physical chemistry, is a concept relating to the phenomenon of adsorption, and it describes the condition when the electrical charge density on a surface is zero. It is usually determined in relation to an… …   Wikipedia

  • Nernst equation — In electrochemistry, the Nernst equation is an equation that can be used (in conjunction with other information) to determine the equilibrium reduction potential of a half cell in an electrochemical cell. It can also be used to determine the… …   Wikipedia

  • Spectator ion — A spectator ion is an ion that exists as a reactant and a product in a chemical equation. Spectator ions can be observed in the reaction of aqueous solutions of sodium chloride and copper (II) sulfate::2Na+(aq) + 2Cl−(aq) + Cu2+(aq) + SO42−(aq) → …   Wikipedia

  • Isoelectric point — The isoelectric point (pI) is the pH at which a particular molecule or surface carries no net electrical charge. Amphoteric molecules called zwitterions contain both positive and negative charges depending on the functional groups present in the… …   Wikipedia

  • Double layer (interfacial) — A double layer (DL, also called an electrical double layer, EDL) is a structure that appears on the surface of an object when it is placed into a liquid. The object might be a solid particle, a gas bubble, a liquid droplet, or a porous body. The… …   Wikipedia
