(c) Strongly acidic
A solution with pH = 3 is strongly acidic, as values much less than 7 on the pH scale represent high H⁺ ion concentration, indicating a strongly acidic solution.
The pH scale runs from 0 (most acidic) to 14 (most basic), with 7 being neutral. pH 3 is well below 7, indicating a strongly acidic solution — not weakly acidic (which would be closer to 7, e.g., pH 5–6). Remember: lower the pH, higher the H⁺ concentration and stronger the acid.
