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.

Why should the chlorophyll be removed from the leaf?
chlorophyll is a thing that makes the leaf green
Do leaves get there colour from a green pigment called chloride?
Yes, Coloured leaves contain chlorophyll. The leaf cells has chloroplasts that contain chlorophyll. The leaves appear in other colours is because that light contain many colour and when it reflects off the leaves you will see that it is in other colours.
What do you called the pigment that gives the leaf color green?
The green colour of the leaves is from the pigment chlorophyll
What is chlorophyll in a leaf?
Chlorophyll is the green coloration of the leaf and or plant. It is the molecule that absorbs sunlight and uses its energy to make carbohydrates from Carbon Dioxide and Water.
How might the distribution of leaf pigments differ in a leaf that is dark green in color vs one which is lighter green?
A darker green plant means that it has more chlorophyll to photosynthesise. A brighter leaf colour on the other hand shows that, that plant does not require so much chlorophyll to photosynthesise.

What gives the colour to the leaf?
Chlorophyll
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 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
What is the name of the green colour that is meant to be on a leaf?

What happen when leaf boil in alcohol what the alcoholl remove from the leaf?
Boiling a leaf in alcohol removes its chlorophyll, so the leaf loses its green colour.
What substance is used for photosynthesis?
Chlorophyll contained in Chloroplasts is used for photosynthesis, it is also the Chlorophyll which gives the leaf it's green colour.
Why a leaf appear green?
due to presence of green colour photosynthetic pigment known as Chlorophyll
