why does orthoboric acid (H₃BO₃) becomes more strong during titration of NaOH when organic compounds such as glcerol is added ?

Dear student,

Boric acid is soluble in boiling water. When heated above 170 °C, it dehydrates, forming metaboric acid (HBO₂):

H₃BO₃ → HBO₂ + H₂O

Metaboric acid is a white, cubic crystalline solid and is only slightly soluble in water. Boric acid melts at about 236 °C, and when heated above about 300 °C further dehydrates, forming tetraboric acid or pyroboric acid (H₂B₄O₇):

4 HBO₂ → H₂B₄O₇ + H₂O
