Technical data Temperature dependence of conductivity with Cobra SMARTsenseuctivity with Cobra SMARTsenseArticle no: P3060567 ![]()

Principle The electrical conductivity of an electrolytic solution is dependent not only upon the type and concentration of the electrolytes, but also other state values. Thus, an increase in conductivity is generally observed with an increase in temperature. This is fundamentally due to the exponential decrease of the solutions's viscosity. In aqueous solutions a limit is reached at approximately 90 °C. Above this temperature the conductivity again decreases. Benefits
Tasks Determine the temperature dependence of the conductivity of a 10% sodium chloride solution from 20 °C to approximately 60 °C. Learning objectives
