A question I was asked was: "Why is ethanol added to chloroform bottles?". I know that chloroform can be slowly converted to poisonous phosgene gas, and that ethanol is added to prevent phosgene levels from rising. However, the options I was given were:
- It decomposes phosgene by converting it into ethyl carbonate.
- It removes phosgene by converting it into ethyl carbonate
Is there a difference between the two wordings, and is one more correct than the other? The answer is supposedly "decomposes".
