Acid–base reaction liquid ammonia are similar to the reactions in water: Nitric acid can be a base in liquid sulfuric acid: The unique strength of this definition shows in describing the reactions in aprotic solvents; for example, in liquid : Because the solvent system definition depends on the solute as well as on the solvent itself, a particular solute can be either an acid or a base depending on the choice of the solvent: is a strong acid in water, a weak acid in acetic acid, and a weak base in fluorosulfonic acid; this characteristic of the theory has been seen as
Acid–base titration Acid–base titration An acid–base titration is a method of quantitative analysis for determining the concentration of an acid or base by exactly neutralizing it with a standard solution of base or acid having known concentration. A pH indicator is used to monitor the progress of the acid–base reaction. If the acid dissociation constant (p"K"a) of the acid or base dissociation constant (P"K"b) of base in the analyte solution is known, its solution concentration (molarity) can be determined. Alternately, the p"K"a can be determined if the analyte solution has a known solution concentration by constructing a titration curve. Alkalimetry and acidimetry
