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.

What do you called the pigment that gives the leaf color green?

The green colour of the leaves is from the pigment chlorophyll


Why should the chlorophyll be removed from the leaf?

Removing chlorophyll from the leaf can help scientists study other pigments present in the leaf, such as carotenoids and anthocyanins. This can provide insights into the overall health of the plant, its stress response, and environmental factors affecting its growth. Additionally, isolating chlorophyll can be useful in various applications, such as in food and textile industries.


Do leaves get there colour from a green pigment called chloride?

Leaves get their green color from a pigment called chlorophyll, not chloride. Chlorophyll is essential for photosynthesis, the process by which plants convert sunlight into energy. As the seasons change and chlorophyll breaks down, other pigments such as carotenoids and anthocyanins can give leaves their autumn colors.


What colour was the leaf when it was removed from the test tube containing methylated spirit?

When the leaf was removed from the test tube containing methylated spirit, it would typically appear a pale yellow or white. This discoloration occurs because the methylated spirit removes chlorophyll and other pigments from the leaf, effectively bleaching it. This process is often done to prepare the leaf for subsequent testing, such as the iodine test for starch, which would indicate the presence of starch as a blue-black color when iodine is applied.

Why does leaf turn light green when boiled in ethanol?

add the leaf to boiling ethanol in a water bath for a few minutes (the boiling ethanol dissolves the chlorophyll and removes the green colour from the leaf - it turns white so it is easy to see the change in colour) wash with water to rehydrate and soften the leaf

Why is a leaf dark green on one side and light on the other?

Because the amount of chlorophyll in the top of leaf is much greater than the amount of chlorophyll in the bottom of leaf. As the chlorophyll is green in colour that's why the top portion of leaf is more green in colour.

Why does ethanol turn a leaf white?

Ethanol can extract chlorophyll from the leaf, causing it to lose its green color and appear white. Chlorophyll is the pigment responsible for the green color in plants, and when it is removed by ethanol, the underlying white color of the leaf becomes visible.
