Final answer:
A titration is an experiment where a known concentration solution is added to another solution to determine its concentration. It is a quantitative reaction of an acid and a base, and indicators are used to show the completion of the reaction.
Step-by-step explanation:
A titration is an experiment where a volume of a solution of known concentration is added to a volume of another solution in order to determine its concentration. Many titrations are acid-base neutralization reactions. It is a quantitative reaction of an acid and a base. Indicators, which change color in response to the solution composition, are used to show that all the analyte has reacted with the titrant.
