Trisodium pentaborate is a salt that can form as a monohydrate with formula Na3B5O8(OH)2·H2O, which contains the anion dihydroxydopentaborate [B5O8(OH)2]3−.[1]
Its formula may be incorrectly given as Na3B5O8·2H2O, or as 3Na2O5B2O3·4H2O. It may also be called simply sodium pentaborate,[1] but this name is more properly reserved for the compound with elemental formula Na2O·5B2O3·nH2O.
