Titration means determination of concentration or ran of a solution with respect to water and pH of 7.
The process of adding standard solution until the reaction is just comppleted is known as titration, and the substrate to be determined is said to be titrated.
Basiically Titration is slow addition of one solution of a known concentration to a known volume of another solution of unknown concentration until the reactin reaches neutralization.
An acid base titration is a quantitative analysis of acid and bases, through this process and acid or bases of known concentration neutralizes an acid or base of unknown concentration.
