Observations:
- Flame Color: The flame will be pale blue.
- No Soot: There will be no black soot produced around the test tube.
- Condensation: Condensation will be observed on the inner walls of the test tube, indicating the presence of water vapor.
- Heat Release: The test tube will become noticeably warm to the touch, indicating that heat is released during the reaction.
Confirmation of Complete Combustion:
The pale blue flame and the absence of soot are key indicators of complete combustion. A pale blue flame indicates that the carbon in the ethanol has been fully oxidized to carbon dioxide. The absence of soot means that there is sufficient oxygen available for all the carbon to be converted to CO2. The condensation confirms the production of water as a product. The heat release confirms that a chemical reaction has occurred.
