What kind of pH value does the most acidic solution have?
Answer and explanation
Correct answer: Very low
The governing concept is the pH scale, which is inversely related to hydrogen-ion concentration: pH = −log[H⁺]. A more acidic solution has a greater concentration of H⁺ ions and therefore a smaller pH value. Thus the most acidic solution has a very low pH, so option A is correct. A pH of seven is neutral, while a high pH indicates a basic solution.
