Question

a note on estimation of boric acid​

Answer 1

Answer:

This feature is used in analytical chemistry to determine the boron content in aqueous solution by potentiometric titration with a strong base, such as NaOH. Boric acid also dissolves in anhydrous sulfuric acid: B(OH)3 + 6 H2SO4 → B(HSO4)4− + 2 HSO4− + 3 H3O.

Answer 2

Probably the most delicate test is that with tincture of mimosa flowers (L. Robin, ANALYST, 1904, 29, 330), while for larger quantities the presence of boric acid is indicated by a green flame produced on igniting the substance with methyl alcohol or ethyl alcohol and glycerin.

May have skin soothing and restoring benefits, but it is primarily used to improve stability of a formula.
