The phrase "Better Living Through Chemistry" (BLTC) is a variant of a DuPont advertising slogan, "Better Things for Better Living...Through Chemistry". DuPont adopted it in 1935 and it was their slogan until 1982 when the "Through Chemistry" part was dropped. Since 1999, their slogan has been "The miracles of science". [1]
Carl Wilhelm Wagner (25 May 1901 – 10 December 1977) was a German physical chemist.He is best known for his pioneering work on solid-state chemistry, where his work on oxidation rate theory, counter diffusion of ions and defect chemistry led to a better understanding of how reactions take place at the atomic level.
Chain-melted state: Metals, such as potassium, at high temperature and pressure, present properties of both a solid and liquid. Wigner crystal : a crystalline phase of low-density electrons. Hexatic state , a state of matter that is between the solid and the isotropic liquid phases in two dimensional systems of particles.
A vapor can exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid). A supercritical fluid (SCF) is a gas whose temperature and pressure are above the critical temperature and critical pressure respectively. In this state, the distinction between liquid and gas disappears.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Solid–liquid phase change of ethanol–water mixtures Sodium chloride and water form a eutectic mixture whose eutectic point is −21.2 °C [ 8 ] and 23.3% salt by mass. [ 9 ] The eutectic nature of salt and water is exploited when salt is spread on roads to aid snow removal , or mixed with ice to produce low temperatures (for example, in ...
The solid–liquid phase boundary can only end in a critical point if the solid and liquid phases have the same symmetry group. [5] For most substances, the solid–liquid phase boundary (or fusion curve) in the phase diagram has a positive slope so that the melting point increases with pressure.
sludge - waste in a state between liquid and solid. sodicity – (ecology) a measure of the sodium content of soil. Sodic soils are dispersible and are thus vulnerable to erosion. sodification - the build-up in soils of sodium relative to potassium and magnesium in the composition of the exchangeable cations of the clay fraction.
