A laboratory device that is used to automate the process of determining the undetermined concentration of a solution, based on the specific concentration of another solution, is called a titrator.

A laboratory device that is used to automate the process of determining the undetermined concentration of a solution, based on the specific concentration of another solution, is called a titrator. This tool is in the form of simple systems used in routine laboratory analyzes to advanced models that are fully automatic and capable of performing different forms of titrations at the same time.

Investigating the types of titrators and titration systems,
the measurement rules of the KEM automatic potentiometric titrator,
using the continuous reaction between the substance that must be measured in the sample and the substance whose concentration is certain, by measuring the consumption of the reagent when which is immersed, it can be concluded that how much of the substance to be measured is seen in the sample.

In manual analysis, the indicator solution is used to determine the end point based on the color change. With a titrator, a potentiometric (pH) change from an electrode is used to determine the end point.

Different forms of
titration Acid-base
titration Chemists use acid-base titration to determine the content of a specific acid, similar to hydrochloric acid with a base, such as sodium hydroxide, in a liquid.

Oxidation-reduction titration
This method, also called reductive titration, is a method of titration that relies on the gain or loss of electrons within a sample to determine what is in the sample.

Sediment titration
In this form of titration, a reagent is added to the sample until a reaction occurs during which a solid forms a precipitate from the sample or falls from it.

Complexometric titration.
This form of titration is similar to sedimentation titration, in which sediments of solids are formed after adding the reagent.
