Question

What is the dielectric constant of water.

Answer 1

Dielectric constant

• A dielectric material is a material that has the ability to store an electrical charge but has a poor electrical conductivity
• The dielectric constant of a substance is defined as the ratio of the permittivity of the substance to the permittivity of the free space
• It has no unit since it is a ratio of the same quantity of different substance

Dielectric constant of water

• The dielectric constant of water is 78.39. because of this high dielectric constant, water can dissolve ionic compounds or polar compounds in it.
• Hence water is regarded as a universal solvent
