Titrant vs. Analyte — What's the Difference?
By Tayyaba Rehman — Updated on September 18, 2023
A titrant is the solution of known concentration used in titration. The analyte is the substance whose concentration is being determined in the titration.

Key Differences
In the realm of chemistry, titration is a fundamental analytical procedure used to determine the concentration of a specific substance in a sample. The titrant is the solution with a known concentration that's added to a given volume of another solution to determine its concentration. On the other hand, the analyte is the substance in the sample whose concentration is being determined.
When performing a titration, the titrant is typically delivered from a burette into the analyte until the reaction between them is complete. This endpoint can be identified visually with an indicator or by some instrumental means. The volume of titrant used gives insights about the concentration of the analyte.
It's pivotal that the concentration of the titrant is known accurately because this information is used to determine the concentration of the analyte. If the titrant's concentration is off, the calculated concentration of the analyte will also be inaccurate.
In essence, while both the titrant and analyte play crucial roles in titration, their functions are distinct. The titrant provides a reference point with its known concentration, while the analyte's concentration remains the mystery to be uncovered.
In summation, a successful titration hinges on the precise interplay between the titrant and the analyte. Mastery of this technique enables chemists to accurately determine concentrations, which is vital in many scientific and industrial applications.

Common Curiosities
Can the roles of titrant and analyte be reversed?
In principle, yes. What is titrant in one experiment could be analyte in another, depending on the procedure's design.
How do you identify the endpoint of a titration?
The endpoint is when the titrant has fully reacted with the analyte, often indicated by a color change or instrument reading.
Why is the concentration of the titrant so critical?
The known concentration of the titrant allows for accurate determination of the analyte's concentration.
Are titrant and analyte specific to a certain type of titration?
No, these terms apply to all types of titration, whether acid-base, redox, or others.
What happens if too much titrant is added?
Over-adding titrant overshoots the endpoint, leading to inaccurate results about the analyte's concentration.
What is the main function of the titrant in titration?
The titrant is used as a reference solution with a known concentration to determine the concentration of an analyte.
Why is it important to note the volume of titrant used?
The volume of titrant used, combined with its concentration, allows for calculation of the analyte's concentration.
How do you prepare a titrant for titration?
A titrant is typically prepared by dissolving a known amount of solute in a solvent and then standardizing it to confirm its concentration.
What happens if the titrant's concentration is wrong?
An incorrect titrant concentration will lead to inaccurate determination of the analyte's concentration.
Are all titrants liquids?
While most commonly liquid, solid titrants exist and can be used in specific titration procedures.
How is the concentration of an analyte determined after titration?
By using the volume of titrant required to reach the endpoint and its known concentration, the concentration of the analyte can be calculated.
Can multiple analytes be determined in a single titration?
Yes, but it requires careful procedure design and may involve multiple titrants or steps.
Can any solution be used as a titrant?
No, the titrant should react specifically and completely with the analyte for accurate titration results.
Can an analyte be a gas?
Yes, while analytes are often liquids or solids, gases can also be analyzed using specific titration techniques.
Is it always necessary to use an indicator in titration?
Not always. While indicators help visually determine the endpoint, some titrations use instruments to detect when the titrant has fully reacted with the analyte.
