What is Redox Titration?

Redox titration is a method used in labs to find much of a substance, called an analyte, is in a solution. It works by making a reaction between the analyte and another substance called a titrant. Sometimes, scientists use a potentiometer or a special chemical called a redox indicator to help with this process.

The process of redox titration relies on the oxidation-reduction reaction between the titrant and the analyte. It is widely used in laboratories to identify the concentration of unknown analytes.

To assess redox titrations accurately, it is necessary to obtain the shape of the corresponding titration curve. In these types of titrations, it is practical to monitor the reaction potential rather than monitoring the concentration of a reacting species.

Reduction

Reduction is a chemical process in which a substance gains electrons or decreases in oxidation state. It involves the addition of hydrogen or the removal of oxygen from a compound.

The primary features of redox titration during reduction reaction are as follows:

• Reduction involves the gain of electrons by a substance or a decrease in its oxidation state.
• In redox titration, reduction occurs when the analyte gains electrons from the titrant.
• This process often results in a change in color, formation of a precipitate, or release of gas, depending on the specific reaction.

Oxidation

Oxidation is a chemical process in which a substance loses electrons or increases in oxidation state. It involves the addition of oxygen or the removal of hydrogen from a compound.

The primary features of redox titration during oxidation reaction are as follows:

• Oxidation involves the loss of electrons by a substance or an increase in its oxidation state.
• In redox titration, oxidation occurs when the titrant loses electrons to the analyte.
• Similar to reduction, oxidation reactions in redox titration can lead to observable changes such as color changes, formation of precipitates, or release of gases.

Redox titration is a method used to determine the concentration of a substance in a solution by measuring the volume or concentration of another substance that undergoes oxidation-reduction reactions with it.

In this article, we will understand the meaning of redox titration, the reduction and oxidation of redox titration, the principle of redox titration, indicators of redox titration and the molecular equation of redox titration.
