Pure, distilled water is a bad conductor of electricity.
However, on the addition of impurities, the conductivity of the liquid increases substantially.
When the water contains added minerals, electricity can be conducted by the solution.
But the same does not happen for pure water.
Hence, by this process, we can distinguish between pure water and mineral water.
