Question

14. Assertion: A scale for measuring hydrogen ion concentration in a solution is called pH scale. The p in pH
stands for 'potenz' in German, meaning power. On the pH scale, we can measure pH from O
(very acidic) to 14 (very alkaline).
Reason: pH should be thought of simply as a number which indicates the acidic or basic nature of a
solution. Higher the hydronium ion concentration, lower is the pH value.
