2. Conductivity (electrolytic) - Wikipedia

   en.wikipedia.org/wiki/Conductivity_(electrolytic)

   For example, the measurement of product conductivity is a typical way to monitor and continuously trend the performance of water purification systems. The electrolytic conductivity of ultra-high purity water increases as a function of temperature (T) due to the higher dissociation of H 2 O in H + and OH − with T.

3. Purified water - Wikipedia

   en.wikipedia.org/wiki/Purified_water

   Purified water is usually produced by the purification of drinking water or ground water. The impurities that may need to be removed are: inorganic ions (typically monitored as electrical conductivity or resistivity or specific tests) organic compounds (typically monitored as TOC or by specific tests)

4. Ultrapure water - Wikipedia

   en.wikipedia.org/wiki/Ultrapure_water

   Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in manufacturing to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including: organic and inorganic compounds; dissolved and particulate matter; volatile ...

6. Electrical resistivity and conductivity - Wikipedia

   en.wikipedia.org/wiki/Electrical_resistivity_and...

   The conductivity of a water/aqueous solution is highly dependent on its concentration of dissolved salts, and other chemical species that ionize in the solution. Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher ...

7. Conductometry - Wikipedia

   en.wikipedia.org/wiki/Conductometry

   As the titration progresses, the protons are neutralized to form water by the addition of NaOH. For each amount of NaOH added equivalent amount of hydrogen ions is removed. Effectively, the mobile H + cation is replaced by the less-mobile Na + ion, and the conductivity of the titrated solution as well as the measured conductance of the cell ...
