to remove the chlorophyll so that you can notice a colour change when adding iodine to test for starch
A plant is destarched by placing a leaf under investigation in boiling water to get rid of all the excess starch. Then place into boiling ethanol to get rid of excess chlorophyll
78.3 degrees Celsius is the boiling point of ethanol.
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
The boiling point of methanol is lower than the boiling point of ethanol.
it vaporises
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.

no, boiling is a physical change
the ethanol will change colour and the leaf will soften
Whisky contains Ethanol. Ethanol boiling point is 78.3C. So at this temperature whiskey also boils
ethanol has a higher boiling point- of 78°C :)
Boiling point of 1-butanol: 118 0C Boiling point of diethyl ether: 34,6 0C
Ethanol has hydrogen bond where as ether does not.
The boiling point of methanol is lower than the boiling point of ethanol.
plant that produces ethanol are grains like millet
