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]
Pemex Deer Park is an oil refinery located in Deer Park, Texas on the Houston Ship Channel in the Greater Houston area. It is owned and operated by Pemex.. As of December 2017, the plant is the fourth-largest taxpayer [1] and the tenth largest employer [2] in Harris County.
While the biological carbon pump fixes inorganic carbon (CO 2) into particulate organic carbon in the form of sugar (C 6 H 12 O 6), the carbonate pump fixes inorganic bicarbonate and causes a net release of CO 2. [46] In this way, the carbonate pump could be termed the carbonate counter pump.
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.
Bjerrum plot: Change in carbonate system of seawater from ocean acidification Changes in ocean chemistry can have extensive direct and indirect effects on organisms and their habitats. One of the most important repercussions of increasing ocean acidity relates to the production of shells out of calcium carbonate ( CaCO 3 ). [ 4 ]
More than 100 are in the "Houston Heights" neighborhood whose borders are, approximately, Highway I-10 on the South, I-610 on the North, 45 on the East and Durham on the West. The "inner Harris County" area is defined as the rest of the area within the Interstate 610 loop; "outer Harris County" is defined as the rest of Harris County.
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.
