The scale is pH scale
So
If pH tends to zero like 1 or 2 then it's highly acidic else weak acid
Answer:
Strong acids = 0 - 3 pH
Weak acids = 4 - 6 pH
Explanation:
pH is the scale used to measure the acidity of a substance. The pH value less than 7 is acidic ( pH < 7 ).
The pH of strong acids is 0 - 3 pH and the pH of weak acids is 4 - 6 pH.
