摘要	pH of aqueous sodium metaborate and pentaborate solutions were precisely measured as functions of concentration from dilute to supersaturation at 298.15 K. Coupling with Raman spectra of some super-saturation samples, a clear picture of the main polyborates and their equilibria was presented. At least five polyborates B(OH)(3), B(OH)(4)(-), B3O3(OH)(4)(-), B4O5(OH)(4)(2-) and B5O6(OH)(4-) exist in aqueous sodium borate solutions. In supersaturated aqueous sodium pentaborate solutions B5O6(OH)(4)(-), B3O3(OH)(4)(-) and B(OH)(3) are the main polyborates, B(OH)(4)(-), B4O5(OH)(4)(2-) present in a minor concentration. While, in aqueous sodium metaborate solutions, covering all the concentration range, B(OH)(4)(-) is the most important species other polyborate anions are less than 5 %. Relevant interactions mechanisms among polyborates were also suggested.
