Thank you for your question!
The titration is an experimental method which makes it possible to carry out an acid-base neutralization.
In this type of reaction, an acid neutralizes a base (or vice versa). More specifically, aqueous particles of an acid bind with aqueous particles of a base to form a salt.
Titration allows you to find the concentration of an acidic or basic substance by knowing its volume and the volume (and concentration) of an acidic or basic substance used to neutralize it. Slowly, titrant (neutralizing solution of known concentration) is poured into the titrated solution until an acid-base indicator changes color, indicating that the solution has been neutralized. In this way, one can retroactively, through calculations, find the unknown concentration.
The analogy is limited, but it's a bit like if there was a hole (solution) whose volume (concentration) we wanted to know. We could count the number of boilers of a liquid (volume of liquid) to be inserted until the hole is full (the acid-base indicator turns).
