Question

Describe the scale used to measure the acidity of a substance. Demonstrate how you could differentiate a weak acid from a strong one.

Answer 1

The scale is pH scale

• pH scale measures from 7
• pH>7 Basic
• pH<7 is acidic
• pH=7 is neutral

So

If pH tends to zero like 1 or 2 then it's highly acidic else weak acid

Answer 2

Strong acids = 0 - 3 pH

Weak acids = 4 - 6 pH

Step-by-step 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.
