Amongst the following, the form of water with the lowest ionic conductance at is :
Saline water used for intravenous injection
water from a well
distilled water
sea water
Pure water is non conducting. Conductance occurs through water due to the presence of ions. Usually, the water from different sources contain some amount of dissolved salts due to which it is conducting.
Distilled water is de-ionised water and hence it does not conduct electricity
Hence, the option number (3) is correct.
