The main purpose of an acid-base titration is to determine the concentration of an acid or a base and whether the unknown acid or base is strong or weak. 

An acid-base titration is a quantitative analysis technique that’s based on acid base reactions. Researchers determine the concentration of a sample an acid by titrating it with a base of known concentration, or vice versa. Using a burette, the acid or base of known concentration is added very slowly to the base or acid of unknown concentration until there is neutralization.
