2.216 gm mixture of bleaching powder and ethanol, with 91.7% (by W/W) , completely reacts. The resulting formed, when reacted with air, produces (phosgene) gas. The mass of produced is 'M(mg)'. Find M/99.

(Atomic Mass: Ca = 40 u, Cl = 35.5 u, O = 16 u, C = 12 u, H = 1 u)

Answer:
6
Solution:

Mass of CaOCl₂ = 16 mmol

Mass of ethanol = 4 mmol

Since ethanol and CaOCl₂ both react completely with each other

∴ None of them are left unreacted.

Therefore, mmoles of CHCl₃ formed = 6 mmole

This means 6 mmoles of COCl₂ will be formed.

Thus, the mass of COCl₂ formed = .
