Three types of titration?

1. Acid-base titration: In this type of titration, a known concentration of acid or base is added to a solution of unknown concentration until the reaction reaches a neutral pH. The point at which the reaction is neutralized is called the equivalence point.

2. Redox titration: In redox titration, the reaction involves the transfer of electrons between the reactants. A reducing agent is titrated with an oxidizing agent, or vice versa, to determine the concentration of one of the reactants.

3. Complexometric titration: In complexometric titration, a metal ion is titrated with a chelating agent to form a complex. The point at which all of the metal ions have reacted with the chelating agent is called the endpoint. This type of titration is often used to determine the concentration of metal ions in a solution.
