What is the electrical conductivity versus concentration for saline?
As you increase the salinity (salts concentration) of the solution, the conductivity will increase proportionally, too. This is because as concentration increases, more ions (the carriers of the current) are present in solution. For this reason, measuring the conductivity of a water sample is generally the method used to determine the salinity (amount of dissolved salts) of the water. If you’re looking for more detail, I found a PDF document put out by a government agency that you may find useful. www.swrcb.ca.gov/nps/docs/cwtguidance/3130fs.
The limiting conductivity of NaCl could be determined by the relationship: LoNaCl = LoNa+ + LoCl- limiting molar conductivity at infinite dilution: Lo When a current flows in an electrolyte solution, charge is carried by the motion of both anions and cations.
