Question
Explain why $2\%$ ethanol is added to chloroform?
✓
Answer
Inhibitors are substances that decreases the rate of chemical reactions.
e.g. Chloroform forms poisonous substance, carbonyl chloride, by air oxidation.
When $2\%$ ethanol is added to chloroform, the formation of $COCl_2$ is suppressed because ethanol acts as an inhibitor and retards the above reaction.
$[$Note: Chloroform was earlier used as an anaesthetic.$]$
