Specific conductance is defined as the reciprocal of resistance in ohms of 1c.c. of liquid at a specified temperature. Its value for distilled water is about ______________ micro mho/cm3?
Correct answer: D. 1
- A. 50
- B. 100
- C. 10
- D. 1
Explanation
Distilled water has very low ionic content, so its conductivity is only about 1 micromho/cm at ordinary temperature. The stated unit should technically be micromho/cm, not micromho/cm³.
