PH scale given in the attachment detects which acids/bases/solutions are strongly acidic or weakly acidic. PH scale shows the concerntration of acid and bases (strong, weak, neutral).
- 7 is the number on PH scale which is said to be neutral.
- Acidic number is 1 to 6.
- Alkaline number is 8 to 14.
