Question
Give any three methods to prepare carbon monoxide.
✓
Answer
1. Carbon monoxide can be prepared by the reaction of carbon with limited amount of oxygen.
$2 C + O _2 \rightarrow 2 CO$
2. On industrial scale carbon monoxide is produced by the reaction of carbon with air.
3. Pure carbon monoxide is prepared by warming methanoic acid with concentrated sulphuric acid which act as a dehydrating agent.
$HCOOH + H _2 SO _4 \rightarrow CO + H _2 O + H _2 SO _4$
$2 C + O _2 \rightarrow 2 CO$
