Decomposition Reaction
A reaction in which a single compound breaks down into two or more simpler substances.
Acids, Bases & SaltsDegree of Ionisation
The fraction of dissolved electrolyte molecules that have broken into ions at equilibrium.
Stoichiometry & Chemical ReactionsDehydration Reaction
A reaction in which water is removed from a single molecule, generally producing an unsaturated or condensed product.
Biochemistry & Polymer ChemistryDenaturation
The loss of a protein's native three-dimensional structure without breaking its peptide bonds.
Organic ChemistryDiastereomer
A stereoisomer that is not a mirror image of the compound with which it is compared.
Acids, Bases & SaltsDiprotic Acid
An acid that can donate two protons per molecule.
Foundations of ChemistryDistillation
A separation technique that exploits differences in volatility by vaporising a liquid and condensing the vapour in a separate vessel.
Chemical EquilibriumDistribution Law
The principle that a solute distributes itself between two immiscible solvents in a constant ratio at fixed temperature.
Biochemistry & Polymer ChemistryDouble Helix
The structure of DNA, in which two antiparallel polynucleotide strands wind around a common axis.
Organic ChemistryE1 Reaction
A two-step elimination proceeding through a carbocation, which then loses a proton to form an alkene.
Solutions & Colligative PropertiesEbullioscopic Constant
The boiling point elevation produced by a one-molal solution of a non-electrolyte in a given solvent.
Electrochemistry & RedoxElectrode
A conductor through which electric current enters or leaves an electrolyte.
Electrochemistry & RedoxElectrolyte
A substance that produces mobile ions when dissolved or molten and therefore conducts electricity.
Solutions & Colligative PropertiesEmulsion
A colloidal dispersion of one liquid as fine droplets throughout another liquid with which it is immiscible.
Organic ChemistryEnantiomer
One of a pair of stereoisomers that are non-superimposable mirror images of each other.
Thermochemistry & ThermodynamicsEndergonic Reaction
A reaction with a positive Gibbs free energy change, which requires an input of energy to proceed.
Thermochemistry & ThermodynamicsEnthalpy
A thermodynamic state function equal to internal energy plus the product of pressure and volume.
Thermochemistry & ThermodynamicsEnthalpy of Sublimation
The enthalpy change when one mole of a solid converts directly into vapour.
Biochemistry & Polymer ChemistryEnzyme
A biological catalyst, almost always a protein, that accelerates a specific biochemical reaction.
Chemical Kinetics & CatalysisEnzyme Catalysis
Catalysis by protein molecules that bind substrates at a specific active site and lower the activation energy dramatically.
Acids, Bases & SaltsEquivalence Point
The point in a titration at which exactly stoichiometric amounts of the two reactants have been combined.
Solutions & Colligative PropertiesFoam
A colloidal system in which gas bubbles are dispersed throughout a liquid or solid medium.
Organic ChemistryFriedel–Crafts Reaction
The introduction of an alkyl or acyl group onto an aromatic ring using a Lewis acid catalyst.
Electrochemistry & RedoxGalvanisation
The coating of iron or steel with a layer of zinc to protect it from corrosion.
