Chlorine is passed through $100\,\text{cm}^3$ of hot $4.0\,\text{mol dm}^{-3}$ sodium hydroxide until the reaction finishes. $6\text{NaOH(aq)} + x\text{Cl}_2\text{(aq)} \rightarrow y\text{NaCl(aq)} + z\text{NaClO}_3\text{(aq)} + 3\text{H}_2\text{O(l)}$ Which row gives the correct answer?
- A$x = 3$, $[\text{Na}^+] = 4.0\,\text{mol dm}^{-3}$
- B$x = 3$, $[\text{Na}^+] < 4.0\,\text{mol dm}^{-3}$
- C$x = 6$, $[\text{Na}^+] = 4.0\,\text{mol dm}^{-3}$
- D$x = 6$, $[\text{Na}^+] < 4.0\,\text{mol dm}^{-3}$
