boric acid solutions. raman spectroscopy of strongly alkaline solutions has shown the presence of b(oh)− ion, [ ] leading some to conclude that the acidity is exclusively due to the abstraction of oh− from water: [ ] [ ] [ ] [ ] b(oh) + h o ⇌ b(oh)− + h+ (k = × − ; pk = ) or more properly expressed...
close ] reply answer : answer - - : : boron is black or dark brown powder, which is oxidized in air and hinders the oxidation of boron due to the formation of three oxidation two boron film. it can react with fluorine at room temperature without corrosion of hydrochloric acid and hydrofluoric acid aqueous...
