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.
Boracic lint (/ b ɒ ˈ r æ s ɪ k /) is a type of medical dressing made from surgical lint that is soaked in a hot, saturated solution of boracic acid and glycerine and then left to dry. Medical dressing
Boro-glycerine is a transparent yellow, tasteless, [1] compound of boric acid and glycerine. [2] It is a powerful antiseptic and is used primarily in oral and dental applications. Historically, it was also used in the preservation of food. [2]
Borate buffered saline (abbreviated BBS) is a buffer used in some biochemical techniques to maintain the pH within a relatively narrow range. Borate buffers have an alkaline buffering capacity in the 8–10 range. Boric acid has a pK a of 9.14 at 25 °C.
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.
Boric is a chemistry term that refers to substances containing boron, such as: boric acid or orthoboric acid, B(OH) 3; metaboric acid, an acid containing boron, HBO 2; tetraboric acid or pyroboric acid, an acid containing boron, H 2 B 4 O 7; boric oxide, specifically boron trioxide B 2 O 3; a boric ester, or organic borate; Boric may also refer to:
In animals, boric acid/borate salts are essentially completely absorbed following oral ingestion. Absorption occurs via inhalation, although quantitative data are unavailable. Limited data indicate that boric acid/salts are not absorbed through intact skin to any significant extent, although absorption occurs through skin that is severely abraded.
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.
