There are four types of reactions:
- Acid-base titration
Hydrogen ions are transferred from acid to base or hydroxide ions from base to acid, thus bringing about neutralization. The stronger the base or acid, the more well-defined the end-point of the reaction becomes.
- Precipitation titration
In this method, the component to be determined is usually precipated by the titrating agent in the form of an insoluble compound. The end-point can be determined by the appearance of a clear solution or by measuring the conductivity
- Complexation titration
Here, ions combine with other ions or molecules to form soluble complexes that show little dissociation
- Redox titration
In this method, electrons are transferred from reducing agents to oxidation agents
