Secondary Standard

A solution that has been titrated against a primary standard. A standard solution is a secondary standard.

 

Chemical Equilibrium

A state of dynamic balance in which the rates of forward and reverse reactions are equal, there is no net change in concentrations of reactants or products while a system is at equilibrium.

Molecular Weight

The mass of one molecule of a nonionic substance in atomic mass units.

Equivalence Point

The point at which chemically equivalent amounts of reactants have reacted.

Strong Field Ligand

Ligand that exerts a strong crystal or ligand electrical field and generally forms low spin complexes with metal ions when possible.

Leveling Effect

Effect by which all acids stronger than the acid that is characteristic of the solvent react with solvent to produce that acid, similar statement applies to bases. The strongest acid (base) that can exist in a given solvent is the acid (base) characteristic of the solvent.

Deuterium

An isotope of hydrogen whose atoms are twice as massive as ordinary hydrogen,deuterion atoms contain both a proton and a neutron in the nucleus.

Meniscus

The shape assumed by the surface of a liquid in a cylindrical container.

Polarimeter

A device used to measure optical activity.

Heat of Solution

The amount of heat absorbed in the formation of solution that contains one mole of solute, the value is positive if heat is absorbed (endothermic) and negative if heat is released (exothermic).
