The Henderson–Hasselbalch equation relates the pH of a solution containing a mixture of the two components to the acid dissociation constant, K a of the acid, and the concentrations of the species in solution. [6] Simulated titration of an acidified solution of a weak acid (pK a = 4.7) with alkali
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.
The Old Bedford River, photographed from the bridge at Welney, Norfolk (2008); the camera is looking downstream, south-west of the bridge. The Bedford Level experiment was a series of observations carried out along a 6-mile (10 km) length of the Old Bedford River on the Bedford Level of the Cambridgeshire Fens in the United Kingdom during the 19th and early 20th centuries to deny the curvature ...
During the experiment, ligand is titrated into the sample cell in precisely known aliquots, causing heat to be either taken up or evolved (depending on the nature of the reaction). [9] Measurements consist of the time-dependent input of power required to maintain equal temperatures between the sample and reference cells.
The design was based on the Abbot's Kitchen at Glastonbury and it adopted the same name despite being a laboratory. The building was one of the first ever purpose-built chemical laboratories anywhere and was extended in 1878. The Abbot's Kitchen in Oxford was expanded considerably in 1957 to become the main Inorganic Chemistry Laboratory (ICL). [5]
Schematic diagram of Gouy balance. The Gouy balance, invented by the French physicist Louis Georges Gouy, is a device for measuring the magnetic susceptibility of a sample. . The Gouy balance operates on magnetic torque, by placing the sample on a horizontal arm or beam suspended by a thin fiber, and placing either a permanent magnet or electromagnet on the other end of the arm, there is a ...
Ab initio quantum chemistry methods are a class of computational chemistry techniques based on quantum chemistry that aim to solve the electronic Schrödinger equation. [1] Ab initio means "from first principles" or "from the beginning", meaning using only physical constants [2] and the positions and number of electrons in the system as input.
[1] [6]: 17 The non-profit Educational Service Incorporated, which became Education Development Center, was created to continue the work of PSSC. By the 1964–1965 school year, about half the US students enrolled in high school physics (200,000 students, 5000 teachers) were reportedly using the PSSC course materials. [6]
