Boric acid, mixed with borax Na2B4O7·10H2O (more properly Na2B4O5(OH)4·8H2O) in the weight ratio of 4:5, is highly soluble in water, though they are not so soluble separately. [19] Boric acid also dissolves in anhydrous sulfuric acid according to the equation: [7]

2.0 Boric Acid Solubility 2.1 Water Boric acid, H3BO3, is moderately soluble in water (roughly 0.4 M at 0 ºC, 0.9 M at 25 ºC and 3 M at 80 ºC). Due to its negative heat of solution, the solubility of boric acid in water increases with temperature. Solubility data reported from several sources (Linke, 1958, Perry, 1997, Lange,

Boric acid will form soluble salts with monovalent cations (e.g. Na2B407.1OH20, 6% in water) and insoluble salts with divalent cations (e.g. CaB407.6H20, almost insoluble in cold water).

Under standard conditions for temperature and pressure (STP), boric acid exists as a white, crystalline solid that is fairly soluble in water. The solubility of H3BO3 in water is temperature-dependent. At a temperature of 25 °C, the solubility of boric acid in water is 57 g/L.

Boric acid is easily soluble in water (Table 2) and is not easily oxidized or decomposed. Due to the electron-deficient structure (Lewis acid) of boric acid and borate, they easily form...

Percentage by weight of solution, in terms of fully hydrated salts. Note: Formulae listed represent the solid phases present at the corresponding temperatures and are not used in calculations. *Kernite may be formed upon slowly lowering of the temperature of a saturated solution.

2006年4月22日 · The solubility of boric acid [B] in LiCl, NaCl, KCl, RbCl, and CsCl was determined as a function of ionic strength (0–6 mol ⋅ kg −1) at 25 ∘ C. The results were examined using the Pitzer equation.

1993年3月1日 · These data, together with solubility data of chloride salts in aqueous solutions of boric acid, are used to parameterize a general thermodynamic model which uses the Wilson equation, along with contributions from Debye-Huckel and a Born term, in order to express the activity coefficients.

2001年4月15日 · Heating boric acid above 100 °C gradually produces metaboric acid, HBO 2; at higher temperatures all water is lost and boron oxide, B 2 O 3, results. Solubility: sol cold water (1 g in 18 mL), boiling water (1 g in 4 mL), cold alcohol (1 g in 18 mL), boiling alcohol (1 g in 6 mL), glycerol (1 g in 6 mL), acetone (1 g in 15 mL).
