Solutions & Colligative PropertiesCoagulation
The aggregation of colloidal particles into clusters large enough to settle out of the dispersion.
Biochemistry & Polymer ChemistryCoenzyme
A small organic molecule that binds temporarily to an enzyme and is essential for its catalytic activity.
Biochemistry & Polymer ChemistryCofactor
A non-protein chemical component required for an enzyme to function.
Solutions & Colligative PropertiesColligative Properties
Solution properties that depend only on the number of dissolved solute particles, not on their chemical identity.
Chemical Kinetics & CatalysisCollision Frequency
The number of collisions occurring per unit volume per unit time in a reacting mixture.
Chemical Kinetics & CatalysisCollision Theory
The model that explains reaction rates in terms of the frequency, energy and orientation of collisions between reacting particles.
Solutions & Colligative PropertiesColloid
A heterogeneous mixture in which particles between 1 and 1000 nm are dispersed through a continuous medium.
Analytical Chemistry & SpectroscopyColumn Chromatography
A preparative technique in which a mixture is separated by passing it down a vertical column packed with stationary phase.
Stoichiometry & Chemical ReactionsCombination Reaction
A reaction in which two or more substances unite to form a single product.
States of Matter & Gas LawsCombined Gas Law
The relation linking pressure, volume and temperature for a fixed amount of gas undergoing a change of state.
Chemical EquilibriumCombining Equilibrium Constants
The rule that when two reactions are added, their equilibrium constants multiply.
Stoichiometry & Chemical ReactionsCombustion Analysis
A technique that determines the empirical formula of an organic compound by burning it completely and weighing the CO₂ and H₂O produced.
Stoichiometry & Chemical ReactionsCombustion Reaction
The rapid exothermic reaction of a substance with oxygen, usually producing heat and light.
Chemical EquilibriumCommon Ion Effect
The suppression of the ionisation or dissolution of a substance by adding a second substance that supplies one of the same ions.
Stoichiometry & Chemical ReactionsComplete Ionic Equation
An equation showing every soluble strong electrolyte as its separate constituent ions.
Inorganic & Coordination ChemistryComplex Ion
A charged species consisting of a central metal ion surrounded by a definite number of ligands.
Chemical EquilibriumComplex Ion Equilibrium
The equilibrium between a metal ion, its ligands and the resulting complex ion in solution.
Chemical Kinetics & CatalysisComplex Reaction
An overall reaction that proceeds through two or more elementary steps.
Acids, Bases & SaltsComplex Salt
A salt containing a complex ion that retains its identity in solution rather than dissociating into simpler ions.
Analytical Chemistry & SpectroscopyComplexometric Titration
A titration based on the formation of a stable complex between the analyte metal ion and a chelating titrant.
Foundations of ChemistryCompound
A pure substance formed when two or more different elements combine chemically in a fixed, whole-number mass ratio.
States of Matter & Gas LawsCompressibility Factor
The ratio of the actual molar volume of a gas to that predicted by the ideal gas law.
Stoichiometry & Chemical ReactionsComproportionation Reaction
A redox reaction in which two species of the same element in different oxidation states combine to give a single intermediate state.
