What is the dielectric constant of water at 25 degrees Celsius, which allows it to effectively screen electrostatic interactions between dissolved ions?
Explanation
Water's high dielectric constant (78.5) is a measure of its ability to insulate opposite charges from each other. This property is crucial for dissolving salts and other charged biomolecules by weakening the electrostatic forces that would otherwise hold them in a crystalline lattice.
