• What is the scale pH is measured on?

pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base

• What ph level does water have is water acidic?

Neutral

• What is the most acidic ph level?

0 is the most acidic level

• What is the most basic ph level?

14 is the most alkaline level.

-----------------------------------------------------------

If there is more hydrogen ion it is acidic, and if there is more hydroxyl ions it means it is alkaline. 6 is the weakest acid and 8 is the weakest alkaline. Hydrochloric acid is the acid that helps digest the food you eat.
