Definition of undissociated in English:
undissociated
adjectiveˌʌndɪˈsəɪʃɪeɪtɪdˌəndɪˈsoʊʃiˌeɪtɪd
Chemistry (of a molecule) not dissociated into oppositely charged ions.
Example sentencesExamples
- Production of the weak acid nitrite and excretion of undissociated nitric acid may help to stabilize cytosolic pH.
- However, if the acid is titrated against a dilute base, the undissociated molecules progressively dissociate and eventually the total hydrogen ion concentration can be found.
- Some substances, such as weak acids or bases in their undissociated form, are soluble in lipids and will dissolve in the lipid bilayer of the cell membrane.
- At pH 8.9, it was a mixture of undissociated molecules, monoanion and dianion.
- Weak acids vary in strength from those which exist primarily as hydrated molecules and only ionize to a very small extent to those which ionize substantially and are in equilibrium with only a small amount of undissociated molecules.
