Electrical Conductivity

This is a measure of a material or substances ability to conduct an electrical current.  Conductivity is the inverse of resistivity.  Metal is considered to have high conductivity (silver being the highest with a reading of 63.01 × 106sm-1) and glass is considered to have fairly low conductivity.

Pure water has very low conductivity. However, water is able to conduct electricity more effectively due to dissolved ions such as minerals, salts and carbon dioxide which may be in the water as pure water does not usually exist in nature.
