Question

(a) what does pH scale measure?
(b)what is its range ?
(c)state the significance of highest and lowest values of PH value ​

Answer 1

Answer:

pH scale measure the acidic and basic level of substance or liquid

It range from 0 - 14

This pH test measures the amount of hydrogen ions that exists in a given solution. High concentrations of hydrogen ions yield a low pH (acidic substances), whereas low levels of hydrogen ions result in a high pH (basic substances).

So the highest value 14 is basic and lowest value 0 is acidic...

Answer 2

Answer:

pH is a measure of the acidic or basic (alkaline) nature of a solution (concentration of the hydrogen ion [H+] activity in a solution determines the pH). The pH scale ranges from 0 to 14, which is the most acidic, a pH of 7 is neutral, and 14 is the most alkaline.
