What solution usually goes in the burette in titration?

The titrant is a known concentration solution that is placed in the burette, and the analyte is a solution of unknown concentration that is poured into a conical flask. In an acid-base titration, the base, such as sodium hydroxide (NaOH), is often taken in a burette, whereas the acid, such as hydrochloric acid (HCl), is typically taken in a conical flask.

Titration, also known as titrimetry, is a type of quantitative analysis used to determine the concentration of a substance. To determine the endpoint an indicator is used that changes the color of the solution after the endpoint or equivalence point is reached. Based on chemical reactions, there are four types of titrations: acid-base, redox, precipitation, and complexometric titrations.

Which solution is in burette in titration?

When performing titrations, the solution is often placed in a burette, known as a titrant. In analytical chemistry, the titrant is a solution with a known concentration that is added to another solution to measure the concentration of analytes.

The known (concentration) solution is taken in a conical flask, and the solution whose concentration or strength you are trying to determine, i.e., titrant, is taken in a burette.

Titration is performed between two interacting solutions. The purpose is to determine the precise volume of a solution that reacts with a known concentration of other solutions.

Typically, a pipette that can only measure a single fixed volume, such as 10 ml or 20 ml, is used to take the known volume. A small amount of the other solution is taken into the burette and added dropwise into the solution, which is taken in a conical flask. That's why we use a burette in the titration.
