Concept:The pH scale measures the acidity or basicity of a solution based on hydrogen ion concentration.
Explanation:The pH scale ranges from 0 to 14.
A pH of 7 is neutral, such as pure water.
A pH below 7 indicates an acidic solution; lower pH means stronger acidity.
A pH of 0 is the lowest value on the scale, representing the maximum acidity possible in an aqueous solution.
In contrast, a pH of 14 indicates a highly alkaline (or basic) solution.
Thus, a solution with pH = 0 is highly acidic because it contains a very high concentration of hydrogen ions (
H+).
Answer:B. highly acidic solution
