Two monovalent ions of opposite charge attract each other. In which case is the attractive force larger: (1) when they are separated by 8 nm in water (relative permittivity of 80) or (2) when they are separated by a cellular membrane of 8 nm thickness (relative permittivity of 10)? Argue and explain
Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
