Concentrated sulfuric acid acts as a strong acid when it reacts with water. $\text{H}_2\text{SO}_4(\ell) + \text{aq} \rightarrow \text{H}^+(\text{aq}) + \text{HSO}_4^-(\text{aq})$ The ion $\text{HSO}_4^-$ that is produced behaves as a weak acid. $\text{HSO}_4^-(\text{aq}) \rightleftharpoons \text{H}^+(\text{aq}) + \text{SO}_4^{2-}(\text{aq})$ Which of the following statements are correct for $1.0\,\text{mol dm}^{-3}$ sulfuric acid?
- A1, 2 and 3 are correct
- B1 and 2 only are correct
- C2 and 3 only are correct
- D1 only is correct
