What is the purpose of mannitol in determination of boric acid?

$\huge \pink{answer}$

To improve the quality of the titration by a strong base, mannitol is added to the sample to form a complex with boric acid resulting in a medium-strong acid compound with a unique pH jump. This method is suitable for the determination of boric acid in the range of 0.15 to 3.00 g/L.
