Water is a good solvent for dissolving ionic compounds because
general-sciencechemistry
- AIt has a high specific heat
- BIt has no colour
- CIt has a high dipole moment
- DIt has a high boiling point
Explanation
Water is a polar molecule with a high dipole moment (about 1.85 D) and a high dielectric constant (about 80), which lets it surround and stabilise separated positive and negative ions, pulling ionic lattices apart into solution. High specific heat, colourlessness, and a high boiling point do not explain the dissolution of ionic compounds. It is water's polarity — its high dipole moment — that makes it an excellent solvent for ionic substances.
