Wet chlorine gas produced during electrolysis of brine is dehydrated by__________________?
Correct answer: A. Spraying 66° Be H2SO4 counter current to the flow of the gas
- A. Spraying 66° Be H2SO4 counter current to the flow of the gas
- B. Passing it through a bed of diatomaceous earth
- C. Passing it through a bed of silica gel
- D. None of these
Explanation
Wet chlorine is dried by counter-current contact with concentrated sulfuric acid, commonly about 66° Baumé, which absorbs water without reacting significantly with chlorine. Silica gel and diatomaceous earth are not the standard industrial drying medium here.
