Valence bond designation for a complex in which the metal ion utilizes d orbitals for one shell inside the outermost occupied shell in its hybridization.
Isomers
Different substances that have the same formula.
Ionization Isomers
Isomers that result from the interchange of ions inside and outside the coordination sphere.
Inert s-pair Effect
Characteristic of the post-transition minerals; tendency of the outermost s electrons to remain nonionized or un shared in compounds.
Insoluble Compound
A very slightly soluble compound.
Indicators
For acid-base titrations, organic compounds that exhibit different colors in solutions of different acidities; used to determine the point at which reaction between two solutes is complete.
Ionization Constant
Equilibrium constant for the ionization of a weak electrolyte.
Ion Product for Water
Equilibrium constant for the ionization of water, Kw = [H3O+][OH-] =1.00 x 10-14 at 25 °C.
Inhibitory Catalyst
An inhibitor, a catalyst that decreases the rate of reaction.
An equation giving the concentration of a reactant remaining after a specified time; has different mathematical form for different orders of reactants.
Ioniztion
The breaking up of a compound into separate ions.
Ideal Solution
A solution that obeys Raoult's Law exactly.
Insulator
Poor electric and heat conductor.
Intermolecular Forces
Forces between individual particles (atoms, molecules, ions) of a substance.
Isomorphous
Refers to crystals having the same atomic arrangement.
