Want this question answered?
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.
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.
When and acid dissolves, ions are released, and the more ions in the water, the more conductivity it has.
pure water is insulator.
1)what is the relation of total dissolved solid and conductivity of water? 2)What is the difference of the conductivity of treated water and raw water?
Resistivity R is the inverse of conductivity G, R=1/G.
high conductivity
Conductivity water is water purified so that it has very low conductivity. (Makes perfect sense, right?) I have only seen it as a historical term until recently (and it drove me nuts trying to find out what it is-- probably just like you). It is so called because the water itself has a low conductivity, but then you dissolve a solute into the water and measure the conductivity of the solution. So the water is the matrix, hence "conductivity water." In the older documents, there isn't a specification that I have found other than simply having conductivity that is "small compared to the value being measured." In the more recent papers that I read, the term "conductivity" is accompanied by the term "ultrapure" and the specification of having a resistance greater than 18.2 mega-ohms.
Generally a neutral substance is called an inert substance.
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.
Unit of dm water conductivity is microsiemens/cm

ph of DM water is 6.5 to 7.1 conductivity of Dm water is near 000
