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 ...

This is a list of minerals which have Wikipedia articles. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species .
Prima facie (/ ˌ p r aɪ m ə ˈ f eɪ ʃ i,-ʃ ə,-ʃ i iː /; from Latin prīmā faciē) is a Latin expression meaning "at first sight", [1] or "based on first impression". [2] The literal translation would be "at first face" or "at first appearance", from the feminine forms of primus ("first") and facies ("face"), both in the ablative case.
A definition of "matter" based on its physical and chemical structure is: matter is made up of atoms. [17] Such atomic matter is also sometimes termed ordinary matter. As an example, deoxyribonucleic acid molecules (DNA) are matter under this definition because they are made of atoms.
In alchemy and philosophy, prima materia, materia prima or first matter (for a philosophical exposition refer to: Prime Matter), is the ubiquitous starting material required for the alchemical magnum opus and the creation of the philosopher's stone. It is the primitive formless base of all matter similar to chaos, the quintessence or aether.
In his 1687 work Philosophiæ Naturalis Principia Mathematica, Newton defined inertia as a property: . DEFINITION III. The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to persevere in its present state, whether it be of rest or of moving uniformly forward in a right line.
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
