Final answer:
An acid-base titration is an experiment where a volume of a solution of known concentration is added to a volume of another solution with an unknown concentration in order to determine its concentration. The determination of concentration can be done by either titrating unknown alkali solution with a standard acid solution or titrating unknown acid solution with a standard alkali solution. The volume and concentration of the reactant added during the titration can be used to calculate the number of moles and determine the concentration of the unknown solution.
Step-by-step explanation:
An acid-base titration is an experiment where a volume of a solution of known concentration (the titrant) is slowly added to a volume of another solution with an unknown concentration (the analyte) in order to determine its concentration. The titration can be either the determination of the concentration of an unknown alkali solution with the help of a standard acid solution, or the determination of the concentration of an unknown acid solution with the help of a standard alkali solution.
During the titration, a few drops of indicator solution are added to the analyte, which changes color when the neutralization point is reached. This is called the equivalence point, or end point, of the titration. By knowing the volumes of the titrant and the analyte used, as well as the concentration of the titrant, the concentration of the analyte can be calculated using Stoichiometry.
