The commonest test is to check the electrical conductivity between two electrodes. Pure water has very poor conductivity, but the conductivity improves as more ions are dissolved in it. Sea water has a conductivity of around 5 S/m (Siemens per metre) Drinking water has a conductivity of 0.005 - 0.05 S/m . Ultra-pure water has a much lower conductivity of 5.5 x 10-6 S/m - a million times smaller than that of sea water.
Conductivity can be used to calculate the salinity of the water.
Low conductivity is better if you don't want electricity to pass. High conductivity is better if you do want electricity to pass. Also, water itself is actually an insulator (very low conductivity) but the impurities in water can be great conductors. Pure water will stop electric flow, but it is very difficult (outside of a lab) to get truly pure water.
conductivity is not zero because water itself has ions i.e. H+ & OH- so conductivity cannot be zero. even if you use EDI still some conductivity will be left it will be almost negligible but still conductivity will be there.
When and acid dissolves, ions are released, and the more ions in the water, the more conductivity it has.
Pure water has extremely low conductivity but any dissolved salts in the water increase its conductivity. Sea water with 3% salt has a high conductivity of 5 S/m.
yes it does

Water will conduct electricity if salt NaCl is dissolved in it. The conductivity is proportional to the salt concentration, and 3% gives a conductivity of 5 S/m, as in sea water.
Sea water has the best electrical conductivity. Ions from the salt can conduct electricity - but not very well.
Specific conductivity is a measure of the ability of water to conduct an electrical current. It is highly dependent on the amount of dissolved solids (such as salt) in the water. Pure water, such as distilled water, will have a very low specific conductance, and sea water will have a high specific conductance.
Conductivity can be used to calculate the salinity of the water.
Unit of dm water conductivity is microsiemens/cm

Tap Water has higher conductivity compared to deionized water since it has more mineral/ salts. Deionized water has less/ no minerals to conduct electrical current. One can experiment this in a your Water Fuel Cell using deionized water, tap water and water with salts like (KOH or NaOH) or sea water.Nitinwww.HydroxyGarage.comWater Fuel Technology is Here !!!
