Which pH value describes an acidic solution?

Explanation:
Acidity is shown by values below 7 on the pH scale. The scale measures hydrogen ion concentration, with lower numbers indicating more H+ ions. A solution with pH 5 has more hydrogen ions (around 10^-5 M) than a neutral solution (pH 7, about 10^-7 M), so it is acidic. Values at 7 are neutral, and higher numbers like 9 or 14 have far fewer H+ ions and are basic. So the value that describes an acidic solution is the one below 7, specifically pH 5.
