The desirable range of pH for drinking water is

  1. 6.5 to 8.5
  2. 5.0 to 6.5
  3. 6.5 to 7.0
  4. 7.0 to 8.5

Answer

The pH of pure water is 7 (neutral). Water with a pH lower than 7 is considered acidic, and with a pH greater than 7 is considered basic (alikaline).

The normal range for pH in surface water is 6.5 to 8.5. Consuming excessively acidic or alkaline water is harmful.
