WebThe conductivity of a pure compound depends on its state and the nature of its chemical bonding. One particular group of compounds is insulators in the pure solid state but become conductors when melted or dissolved in water. In order for water to conduct electrical current, charged particles must be present in the water. WebJul 11, 2024 · Conductivity is a measure of the ability of water to pass an electrical current. Because dissolved salts and other inorganic chemicals conduct electrical current, conductivity increases as salinity increases. Organic compounds like oil do not conduct electrical current very well and therefore have a low conductivity when in water. …
