Amongst the following, the form of water with the lowest ionic conductan at 298 K is:
Electrochemistry · Class 12 · JEE Main Previous Year Question
Amongst the following, the form of water with the lowest ionic conductan\ce at 298 K is:
- a✓
distilled water
- b
saline water used for intravenous injection
- c
water from a well
- d
sea water
distilled water
Strategy: The ionic conductan\ce of water depends primarily on the concentration of dissolved ions (impurities). Lower the solute concentration, lower the conductan\ce.
Comparison:
- Sea water: Contains the highest concentration of ions (~3.5% salts).
- Saline water: Contains 0.9% .
- Well water: Contains various minerals (calcium, magnesium, etc.).
- Distilled water: Purified by evaporation and condensation; essentially free of mineral ions.
Sin\ce distilled water is the most pure among the choi\ces, it has the lowest ionic conductan\ce.
