How will you test ethyl alcohol?
Solution
Ethanol reacts with sodium metal to form sodium ethoxide and leads to evolution of hydrogen gas.
To test whether the given sample is ethanol or not, the following steps should be done.
1. Take test sample in a test tube.
2. Drop a small piece of sodium into the test sample.
3. Bubbles of a gas are evolved.
4. Pass the gas being evolved through the soap solution.
5. Take a burning candle near a gas filled bubble.
6. If the burning candle burns with a pop sound, then, it is confirmed that the gas evolved is hydrogen and eventually, that the test sample is ethanol.
