In chemistry and biochemistry, the Henderson–Hasselbalch equation = + ([] []) relates the pH of a chemical solution of a weak acid to the numerical value of the acid dissociation constant, K a, of acid and the ratio of the concentrations, [] [] of the acid and its conjugate base in an equilibrium.
Abbot's Kitchen chemistry laboratory in Oxford Detail of a wood engraving by W. E. Hodgkin of 1855 showing the Abbot's Kitchen. The Abbot's Kitchen in Oxford, England, is an early chemistry laboratory based on the Abbot's Kitchen at Glastonbury Abbey, a mediaeval 14th-century octagonal building that served as the kitchen at the abbey.
Speciation of ions refers to the changing concentration of varying forms of an ion as the pH of the solution changes. [1]The ratio of acid, AH and conjugate base, A −, concentrations varies as the difference between the pH and the pK a varies, in accordance with the Henderson-Hasselbalch equation.
Eric Johnson "Rick" Heller (born January 10, 1946) is the Abbott and James Lawrence Professor of Chemistry and Professor of Physics at Harvard University.Heller is known for his work on time-dependent quantum mechanics, and also for producing digital art based on the results of his numerical calculations.
Amsterdam Density Functional (ADF) is a program for first-principles electronic structure calculations that makes use of density functional theory (DFT). [1] ADF was first developed in the early seventies by the group of E. J. Baerends from the Vrije Universiteit in Amsterdam, and by the group of T. Ziegler from the University of Calgary.
ZINDO is a semi-empirical quantum chemistry method used in computational chemistry.It is a development of the INDO method. It stands for Zerner's Intermediate Neglect of Differential Overlap, as it was developed by Michael Zerner and his coworkers in the 1970s.
Season 3 ended as the school year came to an end but fans shouldn't be too worried about that inevitable time jump. "We always like to do somewhat of a catch up — whether it's visual or verbal.
The fragment molecular orbital method (FMO) was developed by Kazuo Kitaura and coworkers in 1999. [1] FMO is deeply interconnected with the energy decomposition analysis (EDA) by Kazuo Kitaura and Keiji Morokuma, developed in 1976. The main use of FMO is to compute very large molecular systems by dividing them into fragments and performing ab ...
