This parameter is applied in several areas of our daily lives, from recipes to research laboratories and industries in various sectors.

It is up to professionals in the field of science to prepare office 365 database calculate the concentration of solutions to produce medicines, carry out industrial chemical processes, quantitative analyses, treat metals, monitor pollutants in water, and much more.

One of the best ways to find the balance between components is by using titration. Understand why the combination of these two important methods contributes to the quality and reliability of analytical results.


How is titration used to measure the concentration of solutions?
Titration is a common and widely applied method in chemistry to perform quantitative measurements. It is used to accurately and reliably determine the concentration of a chemical species dissolved in a sample.

The process can be done manually or with automated technology. Basically, it consists of adding a reagent (titrant) in a volume whose concentration is known to monitor the resulting reaction.

Based on the type of reaction between titrant and titrate, titration is divided into four categories:

Acid-base titration: used to determine the concentration of acids and bases in a solution. In this type of reaction, the acid or base pair is neutralized. It is widely used to measure the total acidity or specific acids in fermented beverages and foods, wines and juices;
Complexation titration: used in complexation reactions between metal and ligand. It is a widely used application to determine water hardness and the amount of calcium in milk and cheese;
Redox titration: involves the use of a titrant that can act as an oxidizing or reducing agent and quantifies solutions with oxidizing or reducing properties. It has several uses, including determining the free chlorine content in a sample, the presence of heavy metals and other contaminants;
Precipitation titration: involves the formation of a low-solubility product (precipitate) from the reaction between the titrant and the species to be determined. Its application is to determine the amount of minerals in a sample, such as silver, and also the amount of salt and other nutritious minerals in food, such as zinc, calcium and iron.
Calculating components with titration
The calculation of the concentration of solutions with titration is performed by adding a known volume to an Erlenmeyer flask. Then, the titrant is slowly added, and the solution changes color when the reaction is complete.


The color change serves as a reference point to determine the amount of reagent consumed and, consequently, the concentration of the solution.

Why is it recommended to use the titration method?

There are a number of reasons why this method is so popular, starting with its high level of precision and accuracy.

Titration allows us to identify exactly the equivalence point, or the moment at which the titrant and the titrated substance complement each other, since there is a change in the color of the reaction. Accurate determination of this point is crucial to obtain reliable results in concentration calculations.

It is a well-established analytical technique that can be applied to a variety of chemical reactions and used to identify a substance and its quantity in a sample.

Another very important point is the equipment used. Because they are simple and common items, titration is accessible and has a low cost, compared to other methods.
