Fatty Acid
A long-chain carboxylic acid, usually with an even number of carbon atoms.
Stoichiometry & Chemical ReactionsFermentation
The anaerobic enzymatic conversion of sugars into simpler products such as ethanol and carbon dioxide.
Foundations of ChemistryFiltration
A separation technique that removes suspended solid particles from a fluid by passing the mixture through a porous medium.
Analytical Chemistry & SpectroscopyFingerprint Region
The complex lower-frequency part of an infrared spectrum, below about 1500 cm⁻¹, unique to each compound.
Thermochemistry & ThermodynamicsFirst Law of Thermodynamics
The energy of an isolated system is constant; energy can be converted between forms but never created or destroyed.
Chemical Kinetics & CatalysisFirst-Order Reaction
A reaction whose rate is directly proportional to the concentration of a single reactant.
Analytical Chemistry & SpectroscopyFlame Test
A qualitative test in which a sample is heated in a flame and identified by the characteristic colour emitted.
Inorganic & Coordination ChemistryFlux
A substance added during smelting to combine with the gangue and form a fusible slag.
Solutions & Colligative PropertiesFoam
A colloidal system in which gas bubbles are dispersed throughout a liquid or solid medium.
Chemical Bonding & Molecular StructureFormal Charge
The hypothetical charge on an atom in a Lewis structure assuming all bonding electrons are shared equally.
Foundations of ChemistryFormula Unit
The simplest whole-number ratio of ions represented in the empirical formula of an ionic or network compound.
Foundations of ChemistryFractional Distillation
A distillation carried out through a packed or plated column that repeatedly vaporises and condenses the mixture to separate liquids with…
Analytical Chemistry & SpectroscopyFragmentation Pattern
The characteristic set of smaller ions produced when a molecular ion breaks apart in a mass spectrometer.
Electrochemistry & RedoxFree Energy and Cell Potential
The relation linking the Gibbs energy change of a cell reaction to the electromotive force it generates.
Thermochemistry & ThermodynamicsFree Energy and Equilibrium Constant
The relation connecting the standard Gibbs energy change of a reaction to its equilibrium constant.
Organic ChemistryFree Radical
A highly reactive species containing an unpaired electron.
Chemical Kinetics & CatalysisFree Radical Chain Mechanism
A chain mechanism in which the propagating intermediates are species bearing unpaired electrons.
States of Matter & Gas LawsFreezing Point
The temperature at which a liquid becomes a solid, numerically identical to the melting point of the pure substance.
Solutions & Colligative PropertiesFreezing Point Depression
The lowering of a solvent's freezing point caused by dissolved solute particles.
States of Matter & Gas LawsFrenkel Defect
A point defect in which an ion leaves its lattice site and lodges in a nearby interstitial position.
Chemical Kinetics & CatalysisFreundlich Adsorption Isotherm
An empirical relation describing adsorption on heterogeneous surfaces with a distribution of site energies.
Organic ChemistryFriedel–Crafts Reaction
The introduction of an alkyl or acyl group onto an aromatic ring using a Lewis acid catalyst.
Inorganic & Coordination ChemistryFroth Flotation
A concentration method that separates minerals by exploiting differences in how readily their surfaces are wetted.
Electrochemistry & RedoxFuel Cell
An electrochemical cell that generates electricity continuously from a fuel and oxidant supplied from outside.
