The leaf is placed in alcohol to remove chlorophyll and other pigments, making the leaf's structure more visible for testing. This step is crucial for experiments like the iodine test for starch, as it allows the iodine to interact more effectively with the starch present in the leaf tissues. Without removing the chlorophyll, the color of the leaf would interfere with the results of the test.

Why was the leaf placed in alcohol?
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.
What color does the clear alcohol become once the leaf is boiled in it?
It really depends on the type of leaf and the color of the leaf.
What colour does the clear alcohol become once the leaf is boiled in it?
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.
What colour does the clear alcohol become after you boiled the leaf and why?
When you boil a leaf in clear alcohol, the alcohol typically takes on a greenish hue. This color change occurs because chlorophyll and other pigments from the leaf leach into the alcohol during the boiling process. The heat helps to extract these pigments, allowing the clear alcohol to absorb and display the green coloration.
Why is a leaf put in alcohol?
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.
Why is leaf soaked in warm alcohol?
Soaking a leaf in warm alcohol allows for the extraction of pigments, oils, and other compounds from the leaf. This process is often used in scientific experiments or in the production of herbal tinctures to extract the desired properties from the leaf.
What happens to a leaf when placed in the alcohol and what the alcohol removed from it?
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.
What happens to the color of the alcohol when a leaf is boiled in it?
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 happens when you put a leaf in boiling 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.
What happen when leaf boil in alcohol what the alcoholl remove from the leaf?
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.
Why was the leaf placed in alcohol after being in boiling water?
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.
Why did the alcohol turned green when the leaf was put into it?
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.
Why leaf bits will settled in alcohol?
Leaf bits settle in alcohol due to differences in their densities. The alcohol solution has a lower density compared to the leaf bits, causing the bits to sink and settle at the bottom of the container over time. This phenomenon is known as sedimentation.
