2. Boric acid - Wikipedia

   en.wikipedia.org/wiki/Boric_acid

   Boric acid is a weak acid, with pK a (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of 9.24 in pure water at 25 °C. But apparent p K a is substantially lower in swimming pool or ocean waters because of interactions with various other molecules in solution.

3. Dakin's solution - Wikipedia

   en.wikipedia.org/wiki/Dakin's_solution

   Other formulations have been developed over time. In 1916, Marcel Daufresne substituted sodium bicarbonate for Dakin's boric acid as buffering agent. [7] [17] This formulation is the basis of current commercial products. [18] The concentration chosen by Dakin (0.5%) was the maximum highest concentration found tolerable to the skin.

4. TBE buffer - Wikipedia

   en.wikipedia.org/wiki/TBE_buffer

   TBE or Tris/Borate/EDTA, is a buffer solution containing a mixture of Tris base, boric acid and EDTA.. In molecular biology, TBE and TAE buffers are often used in procedures involving nucleic acids, the most common being electrophoresis.

5. Methenamine - Wikipedia

   en.wikipedia.org/wiki/Methenamine

   Methenamine was only used as a urinary antiseptic in cases of acidic urine, whereas boric acid was used to treat UTIs with alkaline urine. [47] The drug name methenamine , a contraction of the chemical or scientific name hexamethylenetetramine , was formally introduced and designated by the United States Pharmacopeia (USP) by 1925 and replaced ...

6. Tetrafluoroborate - Wikipedia

   en.wikipedia.org/wiki/Tetrafluoroborate

   Potassium fluoroborate is obtained by treating potassium carbonate with boric acid and hydrofluoric acid. B(OH) 3 + 4 HF → HBF 4 + 3 H 2 O 2 HBF 4 + K 2 CO 3 → 2 KBF 4 + H 2 CO 3. Fluoroborates of alkali metals and ammonium ions crystallize as water-soluble hydrates with the exception of potassium, rubidium, and cesium.

7. Boro glycerine - Wikipedia

   en.wikipedia.org/wiki/Boro_glycerine

   At a meeting of the Society of Arts, on March 29, 1882, Professor Barff delivered a lecture, in which he announced his discovery of boro-glycerine. Barff had been attempting to find a way in which boric acid, a known antiseptic, could be used to preserve meats, at a time when beef prices were considered high.
