Description of key information
Additional information
Hydrolysis:
The hydrolysis of BF4− occurs stepwise to BF3OH−, BF2(OH)2− , and BF(OH)3− and ultimately B(OH)4− accompanied with the formation of hydrofluoric acid . Due to the strong affinity of boron for fluoride, complete hydrolysis of BF4- occurs at low concentrations, yet with a slow initial step, especially at normal temperature and at a neutral or alkaline pH.
Biodegradation:
The concept of biodegradation does not apply to inorganic substances.
Bioaccumulation:
Given its ionic nature, tetrafluoroboric acid is expected to partition favourably to water rather than organic and fatty media.
Adsorption/desorption:
No significant sorption behaviour is to be expected for potassium tetrafluoroborate or its dissociated/hydrolysed anions.
