What is a titrant?

A titrant is a solution that is used in a titration process to determine the concentration of an analyte in a sample. The titrant is added to the analyte until the reaction between the two is complete, which is indicated by a color change or a change in pH. The volume of titrant required to reach the endpoint of the reaction is used to calculate the concentration of the analyte.

Titrants are typically standardized to ensure their accuracy and reliability in the titration process. They can be either a strong acid or base, or a solution of a known concentration of a particular substance that reacts with the analyte.

Common titrants include acids such as hydrochloric acid or sulfuric acid, bases such as sodium hydroxide or potassium hydroxide, and oxidizing or reducing agents such as potassium permanganate or sodium thiosulfate.

It is important to choose a titrant that reacts specifically with the analyte of interest in order to obtain accurate and reliable results in the titration process.
