Question
Which substance in 1 mol dm⁻³ aqueous solution would have the same hydrogen ion concentration as 1 mol dm⁻³ of hydrochloric acid?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Hydrochloric acid (HCl) is a strong monoprotic acid, so a 1 mol dm⁻³ solution has a hydrogen ion concentration of 1 mol dm⁻³. Nitric acid (HNO₃) is also a strong monoprotic acid, thus a 1 mol dm⁻³ solution will also have a hydrogen ion concentration of 1 mol dm⁻³.
Hint
Identify which acid is strong and releases only one proton (H⁺) per molecule.
