On adding dilute acid to an aqueous solution that contains nitrite ions, $\text{NO}_2^-(aq)$, a mixture of gases is formed. $2\text{H}^+(aq) + 2\text{NO}_2^-(aq) \rightarrow \text{H}_2\text{O}(l) + \text{NO}(g) + \text{NO}_2(g)$ Which statements correctly describe the process?
- A1, 2 and 3 are correct
- B1 and 2 only are correct
- C2 and 3 only are correct
- D1 only is correct
