titration is mixing an "unknown" solution (in which we know the chemical but don't know how much of it is in solution) with a knnown amount of liquid which will bind with that chemical. A titration is performed in a chemical laboratory with a graduated pipette (a long glass tube with markings) that has a stopper at the bottom, almost a precision faucet.

The liquid is added from a column with a stopper at the bottom. The column is very carefully manufactured so that the column of liquid is uniform in diameter (because of the care with which the glass was formed and drawn into a tube). So we measure this liquid and then add it bit by bit to the solution until there is a midpoint and the solution changes chemically (usually the color changes if we are using color to mark the chemical changes).

As we add the liquid bit by bit, we also measure the acidity of the solution using glass probes that are attached to a pH meter.

Since we know the exact amount of the liquid we're adding and the exact pH of the solution at various points as the reaction is being performed, we can graph this and solve the problem for how much chemical was in the solution before we started.

This is "quantitative analysis," the central lab procedure for which titration (adding carefully measured amounts of a known liquid) is the principal process.

It is done to find the normality of a solution and to find the titre value... Im not sure sure bout this answer.
