Question

What are the different types of volumetric titration method?

Answer 1

Titration, often known as volumetric analysis, is an important technique in the field of analytical chemistry. Titration begins with the preparation of a titrant/titrator, which is a standard solution with a set volume and concentration.

Complete answer:
Different types of volumetric titrations can be classified as:
1. Acid-base Titrations-It is a quantitative analysis method for determining the concentration of an acid or base by accurately neutralising them with a known concentration standard solution of either acid or base. It is taken account of using a pH indicator to see how the acid-base reaction is proceeding.
2. Redox Titrations - An oxidation-reduction process is also known as a redox titration. The chemical reaction occurs with a transfer of electrons in the reactive ions of aqueous solutions in this type of titration.
3. Precipitation Titrations - Precipitation titration is based on the formation of an insoluble precipitate when two reacting chemicals are brought into contact.
4. Complexometric Titrations - At an equivalence point, a complexometric titration is performed in which an undissociated complex is formed. There will be no inaccuracy owing to co-precipitations because it is greater than the precipitation titrations.

Note:
Acid-base indicators are substances that change colour as the pH of their surroundings changes. They are also known as pH indicators. Endpoints, also known as equivalence points, are a point in a reaction where the amount of titrant and titrate equivalents become equal.
