Sodium tetrafluoroborate is an inorganic compound with formula NaBF 4.It is a salt that forms colorless or white rhombic crystals and is soluble in water (108 g/100 mL) but less soluble in organic solvents.
6 Na[BF 4] + B 2 O 3 + 6 H 2 SO 4 → 8 BF 3 + 6 NaHSO 4 + 3 H 2 O. Alternatively, boron tribromide converts various organofluorine compounds to organobromines, evolving the trifluoride gas: [13] 3 R–F + BBr 3 → 3 R–Br + BF 3
In the anhydrous form Na 2 TeO 3 the tellurium atoms are 6 coordinate, three Te-O at 1.87 Å and three at 2.9 Å, with distorted octahedra sharing edges. [2] In the pentahydrate, Na 2 TeO 3.5H 2 O there are discrete tellurite anions, TeO 3 2− which are pyramidal. The Te-O distance is 1.85 - 1.86 Å and the O-Te-O angle is close to 99.5°. [3]
