Titration

Titration is the slow addition of one solution of a known concentration (called a titrant) 


to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.

Why is titration done?

A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution.

Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.

What is a titration in chemistry?

Titration, also known as titrimetry,

is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte.

Since volume measurements play a key role in titration, 

it is also known as volumetric analysis
