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 else can I help you with?
What will happen to the boiling leaf when in ethanol what will happen to the leaf and the ethanol?
When you boil a leaf in ethanol, the ethanol will extract the pigments and other compounds from the leaf. The chlorophyll will dissolve in the ethanol, causing the leaf to lose its green color and appear pale. The ethanol will take on the color of the extracted pigments, turning it into a green solution.
What did ethanol do to the leaf?
Ethanol causes the chlorophyll in the leaf to be extracted, leaving behind only the leaf's cellulose structure. This process removes the green color of the leaf, turning it translucent or white.
When a leaf becomes crispy after being boiled in ethanol how do you remove it?
You can remove the crispy leaf by gently lifting it out of the ethanol solution using tweezers or forceps. Be cautious not to damage the leaf during the removal process as it may be fragile after the boiling.
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
What color is absorbed by a green leaf?
A green leaf absorbs most colors in the visible spectrum except for green light, which is reflected. This reflected green light is what gives the leaf its green color.

What happens when green leaf is boiled in water?
it will make holes
What happens to green light an red light when they shine on a green leaf?
When green light shines on a green leaf, the leaf absorbs most of the green light and reflects some of it, giving the leaf its green color. Red light is not absorbed as efficiently by the leaf, so it gets reflected, making the leaf appear green under white light.
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.
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.
When a leaf becomes crispy after being boiled in ethanol how do you remove it?
You can remove the crispy leaf by gently lifting it out of the ethanol solution using tweezers or forceps. Be cautious not to damage the leaf during the removal process as it may be fragile after the boiling.
Why does leaf turn blue black when boiled in ethanol first then iodine?
Boiling in ethanol strips the leaf's waxy outer coating off, then the iodine turns it blue black because it's reacting to the presence of starch, a product of photosynthesis.
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
When light strikes a green leaf how does this explain why leaves appear green?
Light that is white contains all the colours. When the light hits the leaf, it absorbs all the colours apart from the green light which is reflected back out to your eyes. So you see the leaf as green.
What color is absorbed by a green leaf?
A green leaf absorbs most colors in the visible spectrum except for green light, which is reflected. This reflected green light is what gives the leaf its green color.
When white light shines on a green leaf why do you see green?
The green color of a leaf is due to the pigment chlorophyll, which absorbs most colors from white light except for green, which is reflected. This reflected green light is what our eyes perceive, making the leaf appear green.
