Two different tests were performed on an aqueous solution of a salt that has only two ions. After each test, the mixtures formed were filtered and the filtrate was collected. Test 1: adding aqueous silver nitrate acidified with dilute nitric acid produces a yellow precipitate, giving filtrate solution $P$. Test 2: adding dilute sulfuric acid produces a white precipitate, giving filtrate solution $Q$. Which ions are present in the filtrates?
- A$\text{Ba}^{2+}(aq)$ and $\text{Cl}^-(aq)$
- B$\text{Ba}^{2+}(aq)$ and $\text{I}^-(aq)$
- C$\text{Mg}^{2+}(aq)$ and $\text{Cl}^-(aq)$
- D$\text{Mg}^{2+}(aq)$ and $\text{I}^-(aq)$
