ANSWER:
As alcohol is flammable, burning the boiling tube containing the leaf with alcohol directly on the flame causes danger.
EXPLANATION:
- Alcohol is known as ethanol. The boiling point of Ethanol is 78° C which is highly flammable. Usually for testing conditions, Bunsen burners are used for boiling purposes.
- To enable certain reactions in order to occur at a 'higher temperature', water bath is used for the purpose of heating 'flammable chemicals' instead of an open flame to prevent ignition.
