Is iodine and water heterogeneous mixture?
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
When do ethanolic fermentation take place?
When yeast is added to carbohydrates, or sugar solutions, and left at a maximum temperature of 37˚C in an environment without oxygen. Ethanol and carbon dioxide would be produced. However, it is impossible to make pure ethanol as yeast is killed when the mixture contains more than 15% ethanol.
Why methanol is added to ethanol?
To avoid misuse of ethanol for drinking purpose it is denatured with methanol.
What are the solvent and solute in a containing 100g of ethanol and 3g of sucrose?
solvent=ethanol solute=sucrose because sucrose is added to ethanol.
What is the name of the compound that is added to ethene to produce ethanol?
H2o
Where does strawberry jelly come from?
Certain ingredients are added to form a mixture in factories, the mixture is then added to packaging. The packaging is loaded onto a vehicle and then shipped to local supermarkets and stores.Does that answer your question?
What is a denaturation reaction?
Denaturation of ethanol is not a chemical reaction; the denaturated alcohol is a mixture. Undrinkable additives are added to alcohol.
What happens when ethanol is added to soap?
From the experiment, why is a mixture of ethanol and water instead of simply water itself used for saponification? ... Ethanol is the catalyst in saponification C. Ethanol would help the soaps obtained from saponification reaction become more soluble in water D.

What is the chemical formula for rubbing alcohol?
There is no exact formula. Denatured alcohol is mostly pure ethanol (drinking alcohol) which has had something added to make it poisonous (denatured or unnatural) so that it cannot be drunk. Different substances can be added for this purpose... thus no formula.
Why do you think ethanol is used in saponification process?
Ethanol is added to hasten saponification.

What are the solvent and solute in a containing 100g of ethanol and 3g of sucrose?
solvent=ethanol solute=sucrose because sucrose is added to ethanol.
What are the solvent and solute in a sloution containing 100g of ethanol and 3g of sucrose?
solvent=ethanol solute=sucrose because sucrose is added to ethanol.
How ethenol is obtained from corn?
As Corn grows it converts the suns energy, carbon dioxide and water into sugars, cellulose and oxygen. The Corn is harvested and a mash/ slurry of sorts is made and yeasts are added to ferment the sugars into alcohol. The resulting fermented mixture consists of water, ethanol and some methanol (from decomposition of some cellulose). This mixture is between 10 and 15% purity of ethanol. Large scale distillation is then employed to increase the purity of the ethanol to near 100%
