This reaction may be characterized as Lewis acidity of boron toward −, rather than as Brønsted acidity.

This reaction occurs in two steps, with the neutral complex aquatrihydroxyboron B(OH) 3(OH 2) as an intermediate: However, Raman spectroscopy of strongly alkaline solutions has shown the presence of − ions, leading some to conclude that the acidity is exclusively due to the abstraction of OH − from water: B(OH) 3 + HO − ⇌ B(OH) − 4ī(OH) 3 + H 2O ⇌ B(OH) − 4 + H + ( K = 7.3×10 −10 p K = 9.14) The solution is mildly acidic due to ionization of the acids:ī(OH) 3 + H 2O ⇌ − + H 3O + HBO 2 + H 2O ⇌ − + H 3O + When orthoboric acid is dissolved in water, it partially dissociates to give metaboric acid: Heating metaboric acid above about 180 ☌ eliminates another water molecule forming tetraboric acid, also called pyroboric acid ( H 2B 4O 7): 4 HBO 2 → H 2B 4O 7 + H 2Oįurther heating (to about 530 ☌) leads to boron trioxide: H 2B 4O 7 → 2 B 2O 3 + H 2O Aqueous solution

When heated above 140 ☌, orthoboric acid yields metaboric acid ( HBO 2) with loss of one water molecule: B(OH) 3 → HBO 2 + H 2O The reported transition temperatures vary substantially from source to source. When heated, orthoboric acid undergoes a three step dehydration. It is also formed as a by product of hydrolysis of boron trihalides and diborane: B 2H 6 + 6 H 2O → 2 B(OH) 3 + 6 H 2 BX 3 + 3 H 2O → B(OH) 3 + 3 HX (X = Cl, Br, I) Reactions Pyrolysis īoric acid may be prepared by reacting borax (sodium tetraborate decahydrate) with a mineral acid, such as hydrochloric acid: The distance between two adjacent layers is 318 pm. The triclinic form of boric acid consists of layers of B(OH) 3 molecules held together by hydrogen bonds of length 272 pm. The former is the most common the second, which is a bit more stable thermodynamically, can be obtained with a special preparation method. Two crystalline forms of orthoboric acid are known: triclinic and hexagonal. The B-O bond length is 136 pm and the O-H is 97 pm. The three oxygen atoms form a trigonal planar geometry around the boron. However boric acid and borates have been used since the time of the ancient Greeks for cleaning, preserving food, and other activities. Orthoboric acid was first prepared by Wilhelm Homberg (1652–1715) from borax, by the action of mineral acids, and was given the name sal sedativum Hombergi ('sedative salt of Homberg'). The term 'boric acid' is also used generically for any oxoacid of boron, such as metaboric acid HBO 2 and tetraboric acid H 2B 4O 7. It is a weak acid that yields various borate anions and salts, and can react with alcohols to form borate esters.īoric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other boron compounds. It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite. It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid. This cleaning gel is not just durable, it also comes with a product guarantee from the AOO brand.Īvailable here.Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula B(OH) 3. To use this cleaning gel, just place it on the keyboard surface and roll gently for a while.
