24.1. Acids and Alkalis
To appreciate electrochemical techniques of chemical analysis it is necessary to have an understanding of how substances dissociate to form ions.
All acids dissociate when added to water to produce hydrogen ions in the solution, for example, nitric acid:
The extent to which dissociation takes place varies from acid to acid and increases with increasing dilution until, in very dilute solutions, almost all the acid is dissociated.
According to the ionic theory, the characteristic properties of acids are attributed to the hydrogen ...
