उत्तर
Acids have a pH less than 7.
Explanation:
The pH scale measures acidity from 0 to 14, where a value of 7 represents a completely neutral substance, such as pure water. Because acids release a high concentration of hydrogen ions in solution, they always fall below the neutral midpoint, meaning lower pH values indicate much stronger acidity.
