What does the leaf look like after it had been heated with ethanol?
After being heated with ethanol, the leaf may appear wilted or discolored due to the ethanol extracting the pigments from the leaf. The leaf may also become brittle or fragile as a result of the heat and the alcohol treatment.
What does a leaf look like after ethanol?
After being soaked in ethanol, a leaf may appear discolored or faded with a translucent appearance. The waxy cuticle coating on the leaf surface may have been removed, giving the leaf a more pliable texture.
Why water bath must be used while heating ethanol and acetone?
A water bath is used to regulate the temperature during heating to prevent the solvent from reaching its boiling point and potentially igniting. This method provides a safer way to heat volatile solvents like ethanol and acetone without the risk of fire or explosion.
Is talc soluble in ethanol?
No, talc is not soluble in ethanol. Talc is insoluble in polar solvents like ethanol due to its hydrophobic nature and structure, which does not allow it to dissolve in polar solvents like ethanol.
How does baking soda dissolve in ethanol?
Baking soda (sodium bicarbonate) does not dissolve in ethanol. Baking soda is only soluble in water and not in organic solvents like ethanol.

What are the products when ethyl alcohol is heated?
Ethanol when heated with presence of AlCl3 as a catalytic amount undergoes dehydation as result a loss of water giving ethene gas as a major product. This is a simple way of making gaseous alkenes like ethene. If ethanol vapour is passed over heated aluminum oxide powder, the ethanol is essentially cracked to give ethene and water vapour. To make a few test tubes of ethene, you can use this apparatus:

Is hexane soluble in ethanol?
No, because "like" disolves "like". Ethanol is polar. Hexane is nonpolar.
Is Caffeine soluble in ethanol?
Yes, caffeine is soluble in ethanol. Caffeine, being a polar molecule, can dissolve in polar solvents like ethanol, which facilitates its extraction in various applications. This solubility is one reason why caffeine can be effectively extracted from coffee and tea using alcoholic solvents.
What plant produces ethanol?
plant that produces ethanol are grains like millet
Is mannitol soluble in ethanol?
Yes, mannitol is soluble in ethanol. It is typically considered highly soluble in alcohols like ethanol and isopropanol.
What lab equiment is used for heating small amount of substance?
Depending on what is being heated. If its a liquid that isn't combustable (ie. water) its safe just to heat it using a bunsun burner. However if its something lik ethanol that will combust your better using a water bath. If your wanting a set temperature for a solution to be heated at then use an electronic water bath. If you want to get realy fancy use a heated cermic surface. This have like a magnetic stirrer with it as well and you set the temperature.
What does green leaf symbolise?
It stands for it being the green part out of green leaf and fire red. Nothing else.
Can anything catch on fire if left on a steam heated radiator or by being next to it like a window curtain?
No
