Question

Barium chloride dissolving in water at room temperature is explained by which of the following forces?

• A. Dipole-dipole forces between the solid compound and the water molecules
• B. Hydrogen bonding forces between the barium chloride and the hydrogen portions of the water
• C. Dispersion forces between the cations and anions of the barium chloride and the electron dipole moment of the water molecules
• D. Ion-dipole forces between the cations and anions of the barium chloride and the surrounding water molecules

Answer 1

The correct option is D Ion-dipole forces between the cations and anions of the barium chloride and the surrounding water molecules

$BaC{l}_2$ in water exist as $B{a}^{2+}$ & $C{l}^{-}$ in water attraction occur between $B{a}^{2+}$ & $O{H}^{-}$ and $C{l}^{-}$ & $H^{+}$.These are ion dipole forces between cation and anion of $BaC{l}_2$ and the surrounding water molecules. only polar molecules form ion- dipole forces with ionic compound.
