Which one of the following statements is NOT correct?
Options:
- a) A scale measuring hydrogen ion concentration in a solution is called pH scale.
- b) The higher the hydrogen ion concentration in a solution higher is its pH
- c) We can measure pH generally from 0 to 14 on a pH scale.
- d) The ‘p‘ in pH stands for ‘potenz‘ in German meaning power.

correct answer : b)
Explanation:
The pH scale measures hydrogen ion concentration. Higher concentration of hydrogen ions corresponds to lower pH. Thus statement (b) is incorrect.
