Different types of titrations include acid-base, redox, complexometric, and precipitation titrations.

• Acid-base titrations involve the neutralization of an acid with a base or vice versa.

• Redox titrations involve the transfer of electrons between reactants.

• Complexometric titrations involve the formation of a complex between the analyte and titrant.

• Precipitation titrations involve the formation of a precipitate as the endpoint of the titration.
