The dielectric constant of `H_(2)O` is 80. The electrostatic force of attraction between `Na^(+)` and `Cl^(-)` will beA. reduced to `1/40` in water than in airB. reduced to `1/80` in water than in airC. will be increased to 80 in water than in airD. will remain unchanged |

Answer» Correct Answer - B Water is a polar solvent and have dielectric constant 80.As NaCl is a polar compound and like dissolves like so, forces of attraction between `Na^+` and `Cl^-` ion will reduce to `1/80` in water. |
