On the pH scale, we can measure pH from 0 (very acidic) to ______ (very alkaline).
 

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 14.

  • On the pH scale, we can measure pH from 0 (very acidic) to 14 (very alkaline).
  • pH and Nature of Solutions:
    • A pH of 7 indicates a neutral solution (e.g., pure water).
    • A pH less than 7 indicates an acidic solution.
    • A pH greater than 7 indicates a basic (alkaline) solution.
  • Strength of Acids and Bases:
    • The strength of an acid increases as the pH value decreases from 7 to 0. A solution with a pH of 0 is a very strong acid.
    • The strength of a base increases as the pH value increases from 7 to 14. A solution with a pH of 14 is a very strong base.
