Analyzing +4 | -1
On heating 60 mL60 \mathrm{~mL} of a mixture of equal volumes of chlorine and its gaseous oxide and cooling to atmospheric temperature, the resulting gas measured is 75 mL.75 \mathrm{~mL}. Treatment of this resulting gas mixture with caustic soda (absorbs chlorine) solution resulted in contraction to 15 mL.15 \mathrm{~mL}. Assuming that all measurements were made at the same temperature and pressure, deduce the formula of oxide. (Consider that due to heating entire chlorine oxide is decomposed).
View answer and explanation
Correct option: B
Cl2O{Cl}_2 {O}
Option B is correct because the formula of the oxide is Cl2O, which is deduced from the volume changes during heating and treatment with caustic soda.
