Question

What the volume of the saturated solution of barium hydroxide the solubility of ba(oh) using the 0.002 m solution of hcl

Answer 1

Answer:

in if5, considering i to be the central atom, it has 7 valence electrons.

5 of them form sigma covalent bonds with 5,f atoms. and 2 electrons form a lone pair of electrons.

there fore the steric number= no. of sigma bonds+lone pairs.

=5+1=6.

there for the hybridisation is sp3d2 (6 hybrid orbitals)

thus it's configuration is octahedral. however this contains a lone pair of e which are not counted in the structure or geometry.

there for this forms a pyramidal structure with a lone pair
