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.
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.
What was the colour the clear alcohol become once the leaf is boiled in it?
what colour does the clear alcohol become once the leaf is boiled in it
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.
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.
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 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.
How can a succulent grow from a leaf?
A succulent can grow from a leaf through a process called propagation. When a leaf is removed from the plant and placed in soil, it can develop roots and eventually grow into a new plant. This method allows succulents to reproduce and expand their population.
What happens to a leaf cell if it were placed in a highly concentrated salt solution?
The cell would lose water and the membrane would collapse.

Why did leaf had to be boiled in ethanol when testing leaf for starch?
Boiling the leaf in ethanol removes chlorophyll, which can interfere with the test for starch using iodine. This process helps to ensure accurate detection of starch in the leaf tissue without any color interference from chlorophyll.
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.
What is the colour of a leaf when the chlorophyll is removed?
As we know, chlorophyll is what causes the leaf to appear green. From what I know there is a very specific way to extract chlorophyll from leaves. 1. Boil the leaf to kill the cells and arrest all the chemical activity, this also makes it permeable to alcohol and iodine later on. 2. Submerge the leaf in alcohol (ethanol) which is kept in test tube. 3. Put the test tube into the boiling beaker in step one so the alcohol is boiled alone with the leaf in it. The chlorophyll should be extracted as the alcohol turn green. As for the leafs, they usually only appears lighter than it is originally is, which is VERY light green. I have never seen a leaf with absolutely no chlorophyll so can't tell you right here. WARNING: Alcohol in gas form is highly flammable.
