The desirable range of pH for drinking water is
- 6.5 to 8.5
- 5.0 to 6.5
- 6.5 to 7.0
- 7.0 to 8.5
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.
The correct option is A.
