The leaf was placed in alcohol to preserve it and prevent decay. Alcohol acts as a preservative by killing bacteria and other organisms that can cause the leaf to deteriorate.
It really depends on the type of leaf and the color of the leaf.
When a leaf is boiled in clear alcohol, the color of the alcohol can change depending on the pigments present in the leaf. For example, if a green leaf is used, the alcohol may take on a green hue due to the release of chlorophyll and other pigments. Similarly, boiling leaves with red or purple pigments can result in a reddish or purplish tint to the alcohol. The specific color change will vary based on the type of leaf and its pigment composition.
Leaves are often placed in alcohol to preserve and store them for study or observation. The alcohol acts as a fixative, preventing the leaf from decaying and maintaining its structural integrity for long periods of time. Additionally, alcohol can be used to extract and preserve the leaf's pigments or other chemicals for various research purposes.
Soaking a leaf in warm alcohol helps to extract chlorophyll and other pigments from the leaf tissue. The alcohol dissolves these pigments effectively, making it easier to test for the presence of starch or other substances. This process is often used in experiments to demonstrate photosynthesis by revealing the areas of the leaf that have produced starch. Additionally, the warm alcohol helps speed up the extraction process compared to using cold alcohol.
After being heated with ethanol, the leaf may appear wilted or discolored due to the ethanol extracting the pigments from the leaf. The leaf may also become brittle or fragile as a result of the heat and the alcohol treatment.
When a leaf is placed in alcohol, the alcohol acts as a solvent and removes the chlorophyll from the leaf, causing it to lose its green color. Other pigments present in the leaf may remain, giving the leaf a different color appearance.
When a leaf is boiled in alcohol, the chlorophyll in the leaf is extracted and dissolves in the alcohol. The alcohol may change color depending on the pigments present in the leaf, such as turning green if chlorophyll is present.

what colour does the clear alcohol become once the leaf is boiled in it
Apprently, there is no free carbon in alcohol.
When a leaf is placed in boiling alcohol, the alcohol will extract the pigments from the leaf, resulting in coloration of the alcohol solution. This process is used in laboratories for pigment extraction and analysis.
When a leaf is boiled in alcohol, the alcohol extracts compounds such as essential oils, pigments, and other chemical substances from the leaf. This process is known as maceration and it allows for the extraction of specific components from the plant material.
Placing the leaf in alcohol after boiling water helps to remove the chlorophyll from the leaf, making it easier to see the plant's internal structures under a microscope. The alcohol also dehydrates the leaf, preserving it for further examination.
Alcohol is a solvent: It dissolves stuff. The leaf is porous, full of holes. When the leaf is placed in the alcohol, the alcohol gets into the leafs, and dissolves the pigments in the leaf, probably chlorophyll, which is green. This will turn the alcohol green.
When alcohol is heated, it evaporates at a lower temperature than water. This means that when alcohol is heated, it will turn into vapor more quickly than water.
