    en.wikipedia.org/wiki/Bjerrum_plot

    Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...

    Jannik Bjerrum (son of Niels Bjerrum) developed the first general method for the determination of stability constants of metal-ammine complexes in 1941. [1] The reasons why this occurred at such a late date, nearly 50 years after Alfred Werner had proposed the correct structures for coordination complexes, have been summarised by Beck and Nagypál. [2]

  4. CO2SYS - Wikipedia

    en.wikipedia.org/wiki/CO2SYS

    CO2SYS is a family of software programs that calculate chemical equilibria for aquatic inorganic carbon species and parameters. Their core function is to use any two of the four central inorganic carbon system parameters (pH, alkalinity, dissolved inorganic carbon, and partial pressure of carbon dioxide) to calculate various chemical properties of the system.

  6. Total inorganic carbon - Wikipedia

    en.wikipedia.org/wiki/Total_inorganic_carbon

    The aquatic inorganic carbon system is composed of the various ionic, dissolved, solid, and/or gaseous forms of carbon dioxide in water. These species include dissolved carbon dioxide, carbonic acid, bicarbonate anion, carbonate anion, calcium carbonate, magnesium carbonate, and others. The relative amounts of each species in a body of water ...

    The Bjerrum length (after Danish chemist Niels Bjerrum 1879–1958 [1]) is the separation at which the electrostatic interaction between two elementary charges is comparable in magnitude to the thermal energy scale, , where is the Boltzmann constant and is the absolute temperature in kelvins.

    Texas has been the leading state in petroleum production since discovery of the Spindletop oil field in 1901. [11] As of October 2017, the State of Texas (if treated as its own nation) is the 7th largest oil producing nation in the world, with production totaling approximately 3.78 million barrels (600 thousand cubic meters ) per day of oil ...

  9. Bjerrum defect - Wikipedia

    en.wikipedia.org/wiki/Bjerrum_defect

    A Bjerrum defect is a crystallographic defect which is specific to ice, and which is partly responsible for the electrical properties of ice. [1] It was first proposed by Niels Bjerrum in 1952 in order to explain the electrical polarization of ice in an electric field. [ 2 ]
