distilled water

Show Summary Details

Quick Reference

Water purified by distillation so as to free it from dissolved salts and other compounds. Distilled water in equilibrium with the carbon dioxide in the air has a conductivity of about 0.8 × 10−6 siemens cm−1. Repeated distillation in a vacuum can bring the conductivity down to 0.043 × 10−6 siemens cm−1 at 18°C (sometimes called conductivity water). The limiting conductivity is due to self ionization: H2O ⇌ H++OH. See also deionized water.
