Vedclass · Answer

(B) The chemical formula of borax is $Na_{2}[B_{4}O_{5}(OH)_{4}] \cdot 8H_{2}O$.The polyanion unit is $[B_{4}O_{5}(OH)_{4}]^{2-}$.In this structure,there are $4$ boron atoms.Two boron atoms are $sp^{2}$ hybridized,which results in a trigonal planar geometry.Two boron atoms are $sp^{3}$ hybridized,which results in a tetrahedral geometry.Therefore,the structure contains $2$ tetrahedral and $2$ planar triangular units.
