"As we try to make pure water by gradually removing electrolytes, its conductivity gradually decreases. So, if all electrolytes are removed, will its conductivity become zero? No. Why? Because an infinitesimal part of the molecules of water--only about one in 500 million--is ionized as hydrogen ions () and hydroxide ions (). Theoretically, at this point, the conductivity becomes 0.0548 µS/cm at 25 °C. The conductivity of water used in the production of VLSIs in the semiconductor industry is below 0.06 µS/cm-- that＇s water of very high purity indeed. Such water is referred to as ultrapure water. Without going to such an ultrapure level, conductivity of water can be lowered to below 1 µS/cm through a process of deionization. Such water is called ion-exchanged water or deionized water. When we talk about pure water, we refer to water of this level of purity. When water comes in contact with air, carbon dioxide is dissolved in water, causing its conductivity to rise by about 1 µS/cm. This does affect the conductivity of pure water.? 수증기는 전해를 하지 않을 것이고 분자간의 거리가 멀어 전도도가 0으로 나타나겠고 물의 경우에는 다음과 0.0548 마이크로지멘스/센티미터 정도라네요. VLSI 반도체용 순수는 0.06 정도이고..
