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.
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.
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.
The general expression Qualitative Analysis [...] refers to analyses in which substances are identified or classified on the basis of their chemical or physical properties, such as chemical reactivity, solubility, molecular weight, melting point, radioactivity properties (emission, absorption), mass spectra, nuclear half-life, etc. Quantitative Analysis refers to analyses in which the amount ...
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]
The relative activity of a species i, denoted a i, is defined [4] [5] as: = where μ i is the (molar) chemical potential of the species i under the conditions of interest, μ o i is the (molar) chemical potential of that species under some defined set of standard conditions, R is the gas constant, T is the thermodynamic temperature and e is the exponential constant.
Lawrence Henderson was born in Lynn, Massachusetts the son of a business man Joseph Henderson and his wife. He entered Harvard at the age of 16 in 1894. His father was a ship chandler whose principal business was located in nearby Salem, but who also conducted business in Saint Pierre and Miquelon, a French Overseas collectivity off the coast of Canada.
