Acid-Base Titration vs. Redox Titration: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 23, 2023
Acid-base titration determines concentration through neutralization reactions, while redox titration involves oxidation-reduction reactions.
Key Differences
Acid-base titration is a laboratory technique used to determine the concentration of an acid or a base by neutralizing it with a solution of known concentration. Redox titration, on the other hand, determines the concentration of a reducing or oxidizing agent by reacting it with an oxidizing or reducing agent of known concentration, respectively.
In acid-base titration, the endpoint is typically signaled by a pH indicator's color change. In redox titration, the endpoint might be indicated by a color change due to the presence of an indicator or through the use of a potentiometer.
Acid-base titration is governed by the principle that acids react with bases to form water and salt. In contrast, redox titration is based on the transfer of electrons between the titrant and the analyte, leading to oxidation and reduction processes.
The mathematical relationships in acid-base titration are built upon the concept of moles and equivalents of acid and base. In redox titration, the calculations often revolve around the concept of equivalents and electron transfer.
In practical applications, acid-base titration can be used, for example, in determining the amount of acidity or basicity in substances like vinegar or soap. Redox titration, however, finds uses in areas like determining the amount of vitamin C in a solution or the iron content in ore.

Acid-Base Titration
Acid-base titration relies on the formation of water and salt during neutralization.
The salt formation confirmed the completion of the acid-base titration process.
Redox Titration
Redox titration can use potentiometry or color indicators for endpoint detection.
The change in the potassium permanganate's purple color indicated the endpoint in the redox titration.
Acid-Base Titration
It involves neutralizing an acid or base with a solution of known concentration.
Acid-base titration allowed us to neutralize the unknown base with a standard acid solution.
Redox Titration
Redox titration calculations revolve around the transfer of specific numbers of electrons.
The redox titration revealed that two electrons were transferred per molecule during the reaction.
Acid-Base Titration
Acid-base titration uses pH indicators to signal the endpoint.
During the acid-base titration, the phenolphthalein indicator turned pink, indicating the endpoint.
Redox Titration
Redox titration determines the concentration of a reducing or oxidizing agent.
Redox titration helped ascertain the vitamin C content in the orange juice.
Acid-Base Titration
