Record 3 2003-11-21

English

Subject field(s)
  • Chemistry
  • Analytical Chemistry
DEF

An electrode used widely as a reference electrode of known potential, for example, in electrometric measurements of acidity and alkalinity, in corrosion studies, and in the measurements of the potentials of other electrodes. The calomel electrode consists of mercury covered with a layer of paste of mercury chloride in an aqueous solution of potassium chloride.... The calomel electrode is commonly referred to as a half-cell because it includes an aqueous phase of potassium chloride as one arm of the cell to be used in the electric circuit.

CONT

[...] par la méthode électrométrique [...] on détermine au moyen d'un électromètre la force électromotrice d'une pile à deux liquides, l'une étant la solution à étudier, l'autre une solution de référence, de pH zéro, et dans lesquels plongent deux électrodes à hydrogène [...] Il est plus commode d'utiliser d'autres électrodes, telle l'électrode de verre associée à des électrodes au calomel, ou encore l'électrode à la quinhydrone.

Spanish

  • Química
  • Química analítica
DEF

Electrodo de referencia, de potencial conocido, que consta de mercurio, cloruro mercurioso y solución de cloruro potásico, utilizado para la medida de pH y fuerzas electromotrices.

English

Subject field(s)
  • Environmental Studies and Analyses
  • Air Pollution
CONT

Coulometric techniques. SO2 can be detected by measuring the current necessary to maintain an equilibrium concentration of potassium bromide and bromine in an H2SO4 solution. As SO2 is absorbed the bromine concentration will decrease and a current to an electrode is monitored for how much bromine need to be produced to restore the original concentration balance. Sensitivity is adequate for most urban and industrial applications; however, for background rural sampling, the device has been replaced by the next detector.
