Contrast with fixed ion.
Base, a compound that dissociates to produce hydroxyl (OH-) anions when dissolved in water (also called "caustic" or "alkali.
Acid, a compound that dissociates to produce hydrogen (H) cations when dissolved in water.Diffusion in solutions is the most important phenomenon in electrochemistry, but diffusion will also occur in gasses and solids.Inefficiencies may arise from reactions other than the intended reaction taking place at the electrodes, or side reactions consuming the product.E.g., a cation exchange junior golf contests ideas resin containing fixed negative charges with attached mobile sodium ions can be used to remove "hardness" from water if the calcium and magnesium ions are more strongly attracted to the resin and therefore will replace the sodium ions.That is, the "throwing power" is considered "good" when the current distribution is uniform even on an irregularly shaped substrate.Current Efficiency, the fraction, usually expressed as a percentage, of the current passing through an electrolytic cell (or an electrode) that accomplishes the desired chemical reaction.A positively charged ion.

Practically any metal or alloy that can be electroplated can also be used for electroforming.
The mobile ion in ion exchange.During anodic passivation, using linear-sweep voltammetry, the current first increases with potential, then falls to a very small value.The resulting electrolyte (or electrolytic) solution is an ionic conductor of electricity.It may consist of a single atom or a group of atoms bonded together chemically.References 1 unionpedia is a concept map or semantic network organized like an encyclopedia dictionary.Tell a friend about us, add a link to this page, or visit the webmaster's page for free fun content.Active Metal, a metal that is easily oxidized (corroded) in air.It uses a comparison technique to compare a "standard" voltage source to the unknown, under conditions of practically zero current.Electrode The two electronically conducting parts of an electrochemical cell.
