Science — AI-generated practice question

Yes, basic solutions do contain H⁺(aq) ions. However, in a basic solution, the concentration of OH⁻(aq) ions is greater than the concentration of H⁺(aq) ions. Since the basic nature of a solution depends on the relative excess of OH⁻ ions, the solution remains basic despite the presence of some H⁺ ions.

• Examiners expect two clear points: (1) Yes, H⁺ ions are present, and (2) OH⁻ concentration exceeds H⁺ concentration, so the solution is still basic.
• Avoid simply saying "more OH⁻ ions are present" without linking it to why the solution is basic — the relative excess of OH⁻ is the key.
• Do not confuse "presence" with "dominance" — that distinction is the whole answer.
