dispersed phase
A substance in the colloidal stage.dispersion force
Attractive forces that arise as a result of temporary dipoles induced in atoms or molecules. Also referred to as
van der Waals forces or interactions.dispersion medium
The medium where a disperse phase is distributed.dissociate
When ions break apart from a lattice and go into solution.dissolution
The process where water interacts with the ions within the crystal lattice, causing the lattice to break apart.dissolving
When one substance dissolves in another. This process requires there be a solvent and a solute that interact to
produce a homogeneous solution.distillation
A purification process where the components of a liquid mixture are vaporized and then condensed and
isolated.DNA
Deoxyribonucleic acid. Consists of two chains of nucleotides that connect to one another in a double helix.
Contains the genetic information for the accurate production of proteins.double displacement
Typically includes two soluble salts that react with one another in aqueous media. The general form of this
reaction is AB + CD→AD + CB.dry cell battery
Uses a paste in a casing containing two different metals.ductility
Can be stretched, bent, or twisted without breaking.
