Water gas is a mixture of carbon monoxide (CO) and hydrogen (H₂).
It is produced by passing steam over red-hot carbon (like coke or coal) at high temperatures (typically 800-1000°C). The reaction is: H₂O(g) + C(s) → CO(g) + H₂(g).
Water gas is a significant industrial fuel and a source of hydrogen. It is also known as synthesis gas or syngas when the ratio of CO to H₂ is adjusted, as it is used in the synthesis of various organic compounds.
