Boric acid (H3BO3 or HBO2.H2O) is added (in excess) to form a stable and soluble complex with the steam-distilled ammoniagas:
NH3(g) + HBO2.H2O(aq) --> NH3.HBO2(aq) + H2O
which then can be titrated directly with 0.05M sulfuric acid till pH = 5:
2 NH3.HBO2(aq) + H2SO4(aq) --> 2 NH4+ + HBO2.H2O(aq) + SO42-
Note: Boric acid (HBO2.H2O) is a very weak acid pKa=9.3 and is not interfering with the acid/base titration of ammonia.

Does borax contain boric acid?
Yes, borax contains boric acid.
Why did the boric acid not dissolve?
The boric acid did not dissolve because it is a weak acid that has low solubility in water.
Is boric acid a weak acid?
Yes, boric acid is considered a weak acid because it only partially dissociates in water and does not fully donate all of its protons.
Why Hcl uses in the preparation of boric acid?
Hydrochloric acid (HCl) is used in the preparation of boric acid because it reacts with borax (sodium borate) to release boric acid. The reaction between hydrochloric acid and borax allows for the precipitation of boric acid, which can then be collected and purified.
Why mixed glycerin in assy of boric acid?
Glycerin is commonly added to the preparation of boric acid solutions to help dissolve the boric acid more easily in water. Glycerin also helps to stabilize the solution and prevent crystallization of boric acid.
Does boric acid contain starch?
The simple answer is No. Boric acid is also called hydrogen borate, boracic acid or orthoboric acid. It is an inorganic compound and has the chemical formula H3BO3. There is no starch (an organic ommpound) in boric acid.
