14 terms
Isomorphism
The property of two or more different substances crystallising in the same structural form.
Acids, Bases & SaltsIndicator Range
The span of pH over which an indicator's colour visibly changes, roughly one unit either side of its pKa.
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.
Inorganic & Coordination ChemistryIonisation Isomerism
Isomerism arising when an anion inside the coordination sphere exchanges places with the counter ion outside it.
Biochemistry & Polymer ChemistryIsoelectric Point
The pH at which a molecule carries no net electrical charge.
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 EquilibriumIonic Equilibrium
An equilibrium involving ions in solution, such as the dissociation of weak electrolytes or the dissolution of sparingly soluble salts.
Acids, Bases & SaltsIonic Product of Water
The equilibrium constant for the self-ionisation of water, equal to the product of the hydrogen and hydroxide ion concentrations.
Nuclear & RadiochemistryIonising Radiation
Radiation with enough energy to remove electrons from atoms, creating ions.
Chemical Bonding & Molecular StructureIon–Dipole Interaction
The attraction between an ion and the oppositely charged end of a polar molecule.
Thermochemistry & ThermodynamicsIsobaric Process
A process carried out at constant pressure.
Inorganic & Coordination ChemistryIUPAC Nomenclature of Complexes
The systematic rules for naming coordination compounds unambiguously.
Chemical EquilibriumICE Table
A systematic tabulation of Initial, Change and Equilibrium amounts used to solve equilibrium problems.
Solutions & Colligative PropertiesImmiscible Liquids
