X_2 is a greenish yellow gas with an offensive smell used in water purification. It partially dissolves in water to give a solution which turns blue litmus red. When X_2 is passed through NaBr solution, Br_2 is obtained. What happens when X_2 reacts with hot and conc. NaOH ? Give equations. |

Answer» Solution :`X_2` is chlorine which is a yellowish green gas. It dissolves in water forming HCl and HCLO `Cl_2+ H_2O to HCl + HClO` HCl turns BLUE LITMUS to RED . `Cl_2 + 2NaBr to 2NaCl + Br_2` `3Cl_2 + 6NaOH ( " hot and CONC.") to 5NaCl + NaClO_3 + 3H_2O` |
