MCQ
The $pH$ of water is:
- A$9$
- B$3$
- ✓$7$
- D$4$
✓
Answer
Correct option: C.
$7$
Although the $pH$ of pure water is $7$, drinking water and neutral water exhibits a large $pH$ range because it contains dissolved minerals and gases.
Surface waters typically range from $pH\ 6.5$ to $8.5$ while groundwater ranges from $pH\ 6$ to $8.5$. Water with a $pH$ less than $6.5$ is considered acidic.
