ICE Table
A systematic tabulation of Initial, Change and Equilibrium amounts used to solve equilibrium problems.
States of Matter & Gas LawsIdeal Gas
A hypothetical gas whose particles have zero volume and exert no intermolecular forces, obeying pV = nRT exactly at all conditions.
States of Matter & Gas LawsIdeal Gas Law
The equation of state relating the pressure, volume, amount and absolute temperature of an ideal gas.
Solutions & Colligative PropertiesIdeal Solution
A solution in which the interactions between unlike molecules are identical to those between like molecules, so Raoult's law holds at all…
Solutions & Colligative PropertiesImmiscible Liquids
Two liquids that do not dissolve in one another and separate into distinct layers.
Chemical Bonding & Molecular StructureIncomplete Octet
A stable bonding arrangement in which the central atom carries fewer than eight valence electrons.
Acids, Bases & SaltsIndicator Range
The span of pH over which an indicator's colour visibly changes, roughly one unit either side of its pKa.
Biochemistry & Polymer ChemistryInduced Fit Model
The model in which the active site changes shape on substrate binding to achieve a closer fit.
Organic ChemistryInductive Effect
The permanent polarisation of a sigma bond caused by the differing electronegativity of the attached atoms.
Analytical Chemistry & SpectroscopyInductively Coupled Plasma Mass Spectrometry
A technique combining a plasma ion source with a mass spectrometer for ultra-trace multi-element analysis.
Analytical Chemistry & SpectroscopyInfrared Spectroscopy
A technique that identifies functional groups from the infrared frequencies a molecule absorbs as its bonds vibrate.
Chemical Kinetics & CatalysisInhibitor
A substance that decreases the rate of a chemical reaction.
Chemical Kinetics & CatalysisInitial Rate Method
A technique for determining reaction orders by measuring the starting rate in a series of experiments with different initial concentrations.
Atomic Structure & PeriodicityInner Transition Element
An element of the lanthanide or actinide series, in which f orbitals are being filled.
Chemical Kinetics & CatalysisInstantaneous Rate
The rate of a reaction at one particular moment, given by the gradient of the concentration–time curve at that point.
Chemical Kinetics & CatalysisIntegrated Rate Law
The equation obtained by integrating a differential rate law, giving concentration directly as a function of time.
Analytical Chemistry & SpectroscopyIntegration in NMR
The measurement of the area under each NMR signal, which is proportional to the number of nuclei giving rise to it.
Foundations of ChemistryIntensive Property
A property whose value is independent of the amount of substance present.
Chemical Bonding & Molecular StructureIntermolecular Forces
The comparatively weak attractions acting between separate molecules rather than within them.
Thermochemistry & ThermodynamicsInternal Energy
The total kinetic and potential energy of all the particles within a system.
Inorganic & Coordination ChemistryInterstitial Compound
A compound formed when small atoms occupy the spaces between metal atoms in a lattice.
States of Matter & Gas LawsInterstitial Void
An empty space between the packed spheres of a crystal lattice, capable of hosting a smaller ion or atom.
Analytical Chemistry & SpectroscopyIodometry
A redox titration in which iodine liberated by the analyte is titrated with standard thiosulfate.
Foundations of ChemistryIon
An atom or group of atoms carrying a net electrical charge because its electron count differs from its proton count.
