The pH scale measures the acidity of a solution. A solution with pH 2 is considered...

Explanation:
The essential idea is that pH reflects how many hydrogen ions are in solution: lower pH means higher acidity. A pH of 2 means the hydrogen-ion concentration is 0.01 M. Since neutral water is about 1 × 10^-7 M H+, this is 100,000 times more acidic than neutral. That level of acidity is best described as strongly acidic, not neutral or weakly acidic.
