The principle of acid-base titration is based on the neutralization reaction between an acid and a base.
- In this reaction, hydrogen ions (H⁺) from the acid react with hydroxide ions (OH⁻) from the base to form water.
- The titration measures the amount of acid or base needed to completely neutralize the other.
- An indicator is used to show the end point by changing color when neutralization is complete.
In short:
Acid-base titration works on the principle that an acid reacts with a base in a definite ratio, and the end point shows when the reaction is complete.
