ChemicalProcess
type: Class
subclass of: Process
comment: A chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. [Wikipedia]
equivalent class: Reaction
equivalent class: ChemicalReaction

Acidification
type: Class
subclass of: ChemicalProcess
comment: Any process that decreases the pH value of a subtance.

Adsorption
type: Class
subclass of: ChemicalProcess
comment: Adsorption is the accumulation of atoms or molecules on the surface of a material. This process creates a film of the adsorbate (the molecules or atoms being accumulated) on the adsorbent's surface. [Wikipedia]

Calcification
type: Class
subclass of: ChemicalProcess
comment: Any process that increases the calcium concentration of a subtance.

Crystallization
type: Class
subclass of: ChemicalProcess
comment: Crystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas. [Wikipedia]

Dissolution
type: Class
subclass of: ChemicalProcess
equivalent class: Solvation
comment: Dissolution or solvation is the process of dissolving a solid substance into a solvent to yield a solution. [Wikipedia]

Electrolysis
type: Class
subclass of: ChemicalProcess
comment: Electrolysis is a method of using an electric current to drive an otherwise non-spontaneous chemical reaction.

Fluorescence
type: Class
subclass of: Luminescence
comment: Fluorescence is a luminescence that is mostly found as an optical phenomenon in cold bodies, in which the molecular absorption of a photon triggers the emission of another photon with a longer wavelength. The energy difference between the absorbed and emitted photons ends up as molecular vibrations or heat. Usually the absorbed photon is in the ultraviolet range, and the emitted light is in the visible range, but this depends on the absorbance curve and Stokes shift of the particular fluorophore. Fluorescence is named after the mineral fluorite, composed of calcium fluoride, which often exhibits this phenomenon.

Hydrolysis
type: Class
subclass of: ChemicalProcess
comment: Hydrolysis is a chemical reaction during which molecules of water (H2O) are split into hydrogen (H) and hydroxide anions (OH−) in the process of a chemical mechanism.

Leaching
type: Class
subclass of: ChemicalProcess
comment: In general, leaching is the extraction of certain materials from a carrier into a liquid (usually, but not always a solvent).

Neutralization
type: Class
subclass of: ChemicalProcess
comment: In chemistry, neutralization is a chemical reaction (also called a water forming reaction since a water molecule is formed during the process) in which an acid and a base or alkali (soluble base) react to produce salt and water (H2O). During the process, hydrogen ions H+ (a bare proton) from the acid (proton donor) or a hydronium ion H3O+ and hydroxide ions OH_ or oxide ions O2_ from the base (proton acceptor) react together to form a water molecule H2O. [Wikipedia]

Nucleation
type: Class
subclass of: ChemicalProcess
comment: Nucleation is the extremely localized budding of a distinct thermodynamic phase. Some examples of phases that may form via nucleation in liquids are gaseous bubbles, crystals, or glassy regions.

Oxidation
type: Class
subclass of: Reaction
comment: Reaction of a substance with oxygen or incorporation of oxygen into a molecule.

Photolysis
type: Class
subclass of: ChemicalProcess
subclass of: Restriction
  on property: hasProcess
  all values from: Absorption
equivalent class: Photodissociation
equivalent class: Photodecomposition
comment: Photodissociation, photolysis, or photodecomposition is a chemical reaction in which a chemical compound is broken down by photons. It is defined as the interaction of one or more photons with one target molecule. [Wikipedia]

Phosphorescence
type: Class
subclass of: Fluorescence
comment: Continues to glow after light source is removed

Thermoluminescence
type: Class
subclass of: Luminescence
comment: Glows when heated

Titration
type: Class
subclass of: ChemicalProcess
comment: Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of a known reactant.

Triboluminescence
type: Class
subclass of: Luminescence
comment: Glows when struck
