Titration is a fundamental laboratory technique used in chemistry to determine the concentration of an unknown solution. It involves the reaction between two substances, one of which is a known concentration, and the other is an unknown concentration. The goal of titration is to determine the amount of substance required to react with a known amount of another substance. In this article, we will explore what titration helps determine and how it is used in various applications.

Understanding Titration

Titration is a process of adding a known amount of a substance, called the titrant, to a solution of unknown concentration, called the analyte. The titrant is added slowly and carefully until the reaction between the two substances is complete. The point at which the reaction is complete is called the equivalence point. At this point, the amount of titrant added is directly proportional to the amount of analyte present.

What does Titration Help Determine?

Titration helps determine the unknown concentration of an acid or a base. This is achieved by using a known concentration of a strong acid or base as the titrant. The unknown concentration of the analyte is then calculated based on the amount of titrant required to reach the equivalence point.

Types of Titration

There are several types of titration, including:

Acid-base titration: This type of titration involves the reaction between a strong acid and a strong base.
Redox titration: This type of titration involves the reaction between a reducing agent and an oxidizing agent.
Complexation titration: This type of titration involves the reaction between a metal ion and a complexing agent.

How Titration Works

The process of titration involves the following steps:

Preparation of the analyte: The unknown solution is prepared and its volume is measured.
Preparation of the titrant: The known concentration of the titrant is prepared and its volume is measured.
Addition of the titrant: The titrant is added slowly and carefully to the analyte until the reaction is complete.
Determination of the equivalence point: The point at which the reaction is complete is determined using a pH indicator or a colorimetric method.
Calculation of the unknown concentration: The unknown concentration of the analyte is calculated based on the amount of titrant required to reach the equivalence point.
