concentration cell

A concentration cell produces a small voltage as it attempts to reach equilibrium.

A particular type of wet cell known as a concentration cell is important in understanding corrosion.

There are three general types of concentration cells:

He feels that we are closed in, fouled by the numbness of this concentration cell (Meditations).

Concentration cells can form in the deposits of corrosion products, leading to localized corrosion.

This cell acts as a concentration cell with transference where the fluoride transport number is 1.

Concentration cell corrosion occurs when two or more areas of a metal surface are in contact with different concentrations of the same solution.

Bacterial colonies and deposits can form concentration cells, causing and enhancing galvanic corrosion.

Because an order of magnitude concentration difference produces less than 30 millivolts at room temperature, concentration cells are not typically used for energy storage.

A concentration cell is a limited form of a galvanic cell that has two equivalent half-cells of the same material differing only in concentrations.

Concentration cells generate electricity from the thermodynamic free energy that can be extracted from the difference in chemical concentrations of reactants, in the same reaction.

The Electromotive force (EMF) of a concentration cell with transference includes the liquid junction potential.

South Pole ozone profiles are measured by balloon-borne electrochemical concentration cell (ECC) ozonesondes.

The AMTEC thus is an electrochemical concentration cell which converts the work generated by expansion of sodium vapor directly into electric power.

This energy, which can sometimes be harnessed (a simple example is a concentration cell), and the free-energy per molecule is exactly equal to the electrochemical potential difference between the two regions.

A network of eight ozonesonde sites makes weekly ozone vertical profile observations from the surface to about 35 km using electrochemical concentration cell (ECC) ozonesondes.

Primary pH standard values are determined using a concentration cell with transference, by measuring the potential difference between a hydrogen electrode and a standard electrode such as the silver chloride electrode.

Concentration cell methods of chemical analysis compare a solution of known concentration with an unknown, determining the concentration of the unknown via the Nernst Equation or comparison tables against a group of standards.

A concentration cell is an electrochemical cell where the two electrodes are the same material, the electrolytes on the two half-cells involve the same ions, but the electrolyte concentration differs between the two half-cells.

In 1899 he returned to the University of Kansas as assistant professor of chemistry and resumed his work with liquid ammonia in collaboration with Franklin, carrying out a thesis consisting of a study of concentration cells in this solvent.

The heart of the ozonesonde is an electrochemical concentration cell (ECC) that senses ozone as is reacts with a dilute solution of potassium iodide to produce a weak electrical current proportional to the ozone concentration of the sampled air.
