States of Matter & Gas Laws

Isomorphism

The property of two or more different substances crystallising in the same structural form.

Dimensionless
Acids, Bases & Salts

Indicator Range

The span of pH over which an indicator's colour visibly changes, roughly one unit either side of its pKa.

pH = pK_In ± 1 Dimensionless
States of Matter & Gas Laws

Interstitial Void

An empty space between the packed spheres of a crystal lattice, capable of hosting a smaller ion or atom.

r_void / r_sphere = 0.225 or 0.414 Dimensionless
Inorganic & Coordination Chemistry

Ionisation Isomerism

Isomerism arising when an anion inside the coordination sphere exchanges places with the counter ion outside it.

Dimensionless
Biochemistry & Polymer Chemistry

Isoelectric Point

The pH at which a molecule carries no net electrical charge.

pI = (pKa₁ + pKa₂)/2 Dimensionless
Chemical Kinetics & Catalysis

Instantaneous Rate

The rate of a reaction at one particular moment, given by the gradient of the concentration–time curve at that point.

rate = d[A]/dt mol/(L·s)
Chemical Equilibrium

Ionic Equilibrium

An equilibrium involving ions in solution, such as the dissociation of weak electrolytes or the dissolution of sparingly soluble salts.

mol/L
Acids, Bases & Salts

Ionic Product of Water

The equilibrium constant for the self-ionisation of water, equal to the product of the hydrogen and hydroxide ion concentrations.

Kw = [H⁺][OH⁻] = 1.0 × 10⁻¹⁴ mol²/L²
Nuclear & Radiochemistry

Ionising Radiation

Radiation with enough energy to remove electrons from atoms, creating ions.

eV
Chemical Bonding & Molecular Structure

Ion–Dipole Interaction

The attraction between an ion and the oppositely charged end of a polar molecule.

E ∝ q μ / r² kJ/mol
Thermochemistry & Thermodynamics

Isobaric Process

A process carried out at constant pressure.

q_p = ΔH J
