Question
A liquid has a pH of 8. What does this mean?
- It is weakly acidic
- It is weakly alkaline
- It is neutral
- It is strongly alkaline
Hint:
A pH of greater than 7 indicates a base.
The correct answer is: It is weakly alkaline
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.
pH 8 means it is weakly alkaline.
