Titration is method in chemistry for determining concentrations of reactive substances which exist in unknown quantities of a source solution. The process involves slowly adding a known reactant to another solution (for example, a base with an acid of known concentration) until just enough of the reagent has been added to precisely react with all of the original solution. This process is used to calculate the concentration of a reactive substance in the original solution. For example, it can be used to determine the acid dissociation constant (Ka) or base dissociation constant (Kb) of an acid or base, respectively.
