Deposition
The direct conversion of a vapour into a solid without an intermediate liquid phase.
Electrochemistry & RedoxDaniell Cell
The classic galvanic cell consisting of a zinc electrode in zinc sulfate and a copper electrode in copper sulfate.
Chemical EquilibriumDebye–Hückel Limiting Law
The theoretical relation predicting activity coefficients of ions in very dilute solution from their charge and the ionic strength.
Foundations of ChemistryDecantation
The separation of a liquid from a settled solid or a denser immiscible liquid by carefully pouring off the upper layer.
Stoichiometry & Chemical ReactionsDecomposition Reaction
A reaction in which a single compound breaks down into two or more simpler substances.
Acids, Bases & SaltsDegree of Ionisation
The fraction of dissolved electrolyte molecules that have broken into ions at equilibrium.
Stoichiometry & Chemical ReactionsDehydration Reaction
A reaction in which water is removed from a single molecule, generally producing an unsaturated or condensed product.
Biochemistry & Polymer ChemistryDenaturation
The loss of a protein's native three-dimensional structure without breaking its peptide bonds.
Organic ChemistryDiastereomer
A stereoisomer that is not a mirror image of the compound with which it is compared.
Acids, Bases & SaltsDiprotic Acid
An acid that can donate two protons per molecule.
Foundations of ChemistryDistillation
A separation technique that exploits differences in volatility by vaporising a liquid and condensing the vapour in a separate vessel.
Chemical EquilibriumDistribution Law
The principle that a solute distributes itself between two immiscible solvents in a constant ratio at fixed temperature.
Biochemistry & Polymer ChemistryDouble Helix
The structure of DNA, in which two antiparallel polynucleotide strands wind around a common axis.
Atomic Structure & PeriodicityDiagonal Relationship
The similarity in properties between an element of period 2 and the element one place to its lower right in period 3.
