Question: 1 / 400

What is the safe pH range for drinking water?

5.0 to 6.0

6.5 to 8.5

The safe pH range for drinking water is 6.5 to 8.5. This range is considered optimal because it ensures that the water is neither too acidic nor too basic, which can affect the taste, corrosiveness, and overall quality of the water. Water with a pH below 6.5 can be corrosive, leading to leaching of metals and harmful substances from pipes and fixtures. On the other hand, water with a pH above 8.5 can taste bitter and may indicate the presence of alkaline substances that could be harmful if consumed in large quantities. Therefore, a pH range of 6.5 to 8.5 provides a balance that is not only safe for human consumption but also conducive to the integrity of plumbing systems.
