Anomalies of the electrical properties of water -- from the high dielectric constant to anomalous proton mobility.

Advanced Locked #44

The dielectric constant of water and ice is high

Water has one of the highest dielectric constants of any liquid.

Advanced Locked #45

The relative dielectric constant shows a temperature maximum

Instead of falling monotonically, the dielectric constant shows a maximum at a certain temperature.

Advanced Locked #46

The relative dielectric constant shows a kink at 60 degrees Celsius

At 60 degrees Celsius, the temperature dependence of the dielectric constant shows an unexpected change.

Specialist Locked #47

The imaginary part of the dielectric constant has a minimum at 20 K

In the microwave range, the loss factor of ice shows a minimum at very low temperatures.

Advanced Locked #48

The mobility of protons and hydroxide ions is anomalously fast

Protons move through water via the Grotthuss mechanism much faster than other ions.

Advanced Locked #49

The electrical conductivity of water reaches a maximum at 230 degrees Celsius

The intrinsic conductivity of pure water has a maximum at high temperature.

Advanced Locked #50

The electrical conductivity of water increases considerably with frequency

At high frequencies, water shows considerably increased conductivity.

Advanced Locked #54

Water adsorption can cause negative electrical resistance

On certain surfaces, water adsorption leads to an unusual decrease in resistance.
