| Bronsted acid | An acid that is a proton donor. (05 Mar 2000) |
|---|---|
| Bronsted base | Any molecule or ion that combines with a proton; e.g., OH-, CN-, NH3; this definition replaces the older and more limited concepts of base. (05 Mar 2000) |
| Bronsted, Johannes | <person> Danish physical chemist, 1879-1947. See: Bronsted acid, Bronsted base, Bronsted theory. (05 Mar 2000) |
| Bronsted theory | That an acid is a substance, charged or uncharged, liberating hydrogen ions in solution, and that a base is a substance that removes them from solution (e.g., NH4+, CH3COOH, and HSO4- are acids; NH3, CH3COO-, and SO4- are bases); useful in the concept of weak electrolytes and buffers. Compare: Bronsted acid, Bronsted base. (05 Mar 2000) |
| general acid-base catalysis | A catalytic reaction that involves the tranfer of a proton to or from anon-water molecule. (09 Oct 1997) |
| catalysis | <chemistry> The acceleration of a chemical reaction by a catalyst. (16 Mar 1998) |
| heterogeneous catalysis | <chemistry> A form of catalysis in which the catalyst is in different physical state than the reactants. (09 Jan 1998) |
| homogeneous catalysis | <chemistry> A form of catalysis in which the catalyst is in the same physical state than the reactants, for example reactants and catalyst are all gases. (09 Jan 1998) |
| Abbe's law of limiting resolution | <physics> For a periodic structure of units separated by distance d and obliquely illuminated by the unrefracted ray and one of the two diffracted rays (extremely oblique illumination). Abbe applied the law of diffraction: d = 0.5 lambda /NA, where: lambda = wavelength of the monochromic light or shortest of mixed wavelengths NA = the limiting numerical aperture (NA) of objective or condenser. (05 Aug 1998) |
| all or none law | Consistently total response to any effective stimulus. Synonym: all or none law. (05 Mar 2000) |
| American Law Institute formulation | Used in certain jurisdictions to determine criminal responsibility in legal proceedings. See: criminal insanity. (05 Mar 2000) |
| American Law Institute rule | A test of criminal responsibility (1962): "a person is not responsible for criminal conduct if at the time of such conduct as a result of mental disease or defect he lacks substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law." (05 Mar 2000) |
| Ampere's law | <physics> General equation in electromagnetism relating the magnetic field and the currents generating it. The various forms of the equation can be found in an introductory electromagnetism text. (09 Oct 1997) |
| Angstrom's law | A substance absorbs light of the same wavelength as it emits when luminous. (05 Mar 2000) |
| Arndt's law | An obsolete law stating that weak stimuli excite physiologic activity, moderately strong ones favour it, strong ones retard it, and very strong ones arrest it. (05 Mar 2000) |
