उत्तर
An acidic solution has a pH of less than 7.
Explanation:
The pH scale measures the concentration of hydrogen ions (H+) in a solution, ranging from 0 to 14. A pH of exactly 7 is considered neutral, representing pure water. Solutions with a pH less than 7 are acidic because they contain a higher concentration of H+ ions, while solutions with a pH greater than 7 are basic or alkaline.
