What is the pH value of a neutral aqueous solution at standard room temperature?
A. 0
B. 7✓ Correct Answer
C. 14
D. 1
💡 Solution & Explanation
At twenty-five degrees Celsius, a neutral aqueous solution has a pH value exactly equal to 7, where the concentration of hydronium ions equals the concentration of hydroxide ions. Values below 7 indicate acidity, while values above 7 denote basicity. The pH scale ranges logarithmic values from 0 to 14. Pure water serves as the standard neutral reference liquid.
