The conductivity of de-ionized water should have how many microhmos/cm?

De-ionized water is highly purified and is expected to have a very low electrical conductivity, which is indicative of the absence of ionic contaminants. The conductivity of de-ionized water typically measures less than 0.2 microhmos/cm, primarily because the process of de-ionization removes most, if not all, dissolved ions that contribute to conductivity.

This low conductivity is essential in various analytical and laboratory settings, as it ensures that the water does not interfere with test results or reactions that may be sensitive to the presence of ions. In contrast, readings higher than this would suggest that the water may not be sufficiently de-ionized and could contain residual ions that could affect experiments or analyses. Therefore, the correct assertion is that the conductivity of de-ionized water should be less than 0.2 microhmos/cm.
