The electrical conductivity of liquid hydrocarbons can be measured by a precision meter. The electrical conductivity of ionic compounds in the molten (liquid) and aqueous states can be explained below: When the ionic compounds are melted through heating or dissolved in water, the positive and negative ions will break free and become mobile, that is able to move freely. Some liquids such as oil or alcohol do not form ions and do not conduct electricity. This ability of conductance in water is directly proportional to the concentration of the ions present in the water. Additionally, aquarium enthusiasts are concerned with TDS, both for freshwater and salt water aquariums. Typical frequencies used are in the range 13 kHz. Beaker With Blue Liquid image by explicitly from. So its solution conducts electricity. Applications of TDS measurements are not limited to industrial use; many people use TDS as an indicator of the purity of their drinking water. This type of measurement is not ion-specific; it can sometimes be used to determine the amount of total dissolved solids (TDS) if the composition of the solution and its conductivity behavior are known. Solubilities are in water and are reported as grams solvent/100 grams water. Of course it cannot dissolve everything, but it does dissolve more substances than any other liquid, so the term fits pretty well. Presently calculated values of phase shift of some simple and non-simple liquid metals. The electrical conductivity of liquids is a measure of water's capability to allow electrical flow.
