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 ...
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure. It is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
Liquid water is present on Earth, covering 71% of its surface. [23] Liquid water is also occasionally present in small amounts on Mars . [ 186 ] Scientists believe liquid water is present in the Saturnian moons of Enceladus , as a 10-kilometre thick ocean approximately 30–40 kilometers below Enceladus' south polar surface, [ 187 ] [ 188 ] and ...
Liquid consonants are also rarely geminated cross-linguistically. [22] Many languages, such as Japanese, Korean, or Polynesian languages (see below), have a single liquid phoneme that has both lateral and rhotic allophones. [23] English has two liquid phonemes, one lateral, /l/ and one rhotic, /ɹ/, exemplified in the words led and red.
In physics, a fluid is a liquid, gas, or other material that may continuously move and deform (flow) under an applied shear stress, or external force. [1] They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them.
A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. Major uses of solvents are in paints, paint removers, inks, and dry cleaning. [2]

In other words, colligative properties are a set of solution properties that can be reasonably approximated by the assumption that the solution is ideal. Only properties which result from the dissolution of a nonvolatile solute in a volatile liquid solvent are considered. [ 2 ]
