The solution having zero pH will be
Correct answer: C. Highly acidic
- A. Neutral
- B. Basic
- C. Highly acidic
- D. Highly basic
Explanation
The pH scale ranges from 0 to 14 and is used to determine the acidity or basicity of a solution. A pH of 7 is considered neutral, a pH less than 7 is acidic, and a pH greater than 7 is basic. A pH of zero indicates an extremely high concentration of hydrogen ions, making the solution highly acidic. Therefore, the solution with zero pH is highly acidic. The other options are incorrect because neutral solutions have a pH of 7, basic solutions have pH values greater than 7, and highly basic solutions have pH values closer to 14.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
