Ethanol, also called ethyl alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is best known as the type of alcohol found in Alcoholic Beverages and in thermometers. In common usage, it is often referred to simply as alcohol. Important physical and chemical properties are listed.
Physical Properties
- Ethanol or ethyl alcohol is a colourless liquid with a characteristic smell called alcoholic smell.
- It boils at 351 K (78°C).
- It is neutral towards litmus.
Ethanol is highly soluble or miscible with water. The two can mix with any proportion. A solution containing 95% alcohol and 5% water is called rectified spirit. Completely pure or 100% alcohol is called absolute alcohol.
Chemical Properties
- Combustion: Ethanol is highly volatile and combustible liquid. When a flame is bought in its contacts, it immediately catches fire and burns with a blue flame. the products of combustion of ethanol are carbon dioxide and water. C2H5OH(l) + 3O2(g) -----> 2CO2(g) + 3H2O.
- Reaction with sodium metal: Ethanol reacts with sodium metal to form sodium ethoxide. Hydrogen gas is also evolved in the reaction It is accompanied by brisk effervescence. 2C2H5OH(l) + 2Na(s) -----> 2C2H5OHNa(l) + H2(g). Hydrogen gas is always evolved when an alcohol is reacted with a dry piece of sodium metal. Potassium metal also reacts in the same manner.

What 2 physical properties can be used to separate ethanol and water?
density and boiling point
Is ethanol a reactant or a product?
Your question is not right.ethanol is also know as ethyl alcohol. When you take the preparations of ethanol,here it acts as product example ethane reacts with water to give ethanol C2H4+H2O gives C2H5OH in this example ethanol is a product. When we take chemical or physical properties of ethanol it act as reactent in the chemical equation. Example-combustion or burning of ethanol in air gives carbon dioxide and water. C2H5OH+3O2 gives 2CO2+3H20 in the above example ethanol is a reactent.
Ethanol is a stimulant?
Ethanol is a CNS depressant. It is only thought to be stimulating when individuals experience its disinhibiting properties and confuse this with CNS stimulation (which does not occur with ethanol).
Why does ethanol burn differently than ethanol and water mixed?
the main reason why ethanol burns differently then ethanol and water mix is mainly because when you add the water to the ethanol you are making the ethanol less potent so it will burn weaker.
Is ethanol reducing agent?
ethanol is a solvent
What is the color of ethanol in physical properties?
Ethanol i.e. alcohol in its natural state is water white and transparent .

Gasoline is a mixture of hydrocarbons and some additives with antiknocking properties and now ethanol in many places.
How do you difference between ethanol and ethanoic acid?
its quite an easy question. the answer is very simple.......chemical properties of ethanoic acid:-gives effervescence of CO2 with NaHCO3.it belongs to the category of weak acid called the carboxylic acid.chemical properties of ethanol:-doesnt give any effervescence of CO2.it belongs to the category of alcoholphysical properties of ethanoic acid:-its melting point is 290 K, so it often freezes in winters at cold climate.so, pure acetic acid is called glacial acetic acid.physical properties of ethanol:-it doesnt freezes in the winters.may be more but this is all the important ones...:)hope i helped u....
Why ethanol not suitable in Gas chromatography?
Its alcohol so it can purify the chemicals used in the experiment. Furthermore, it will travel up the filter paper better than water will. Ethanol is pure whereas water may have other things in it such as chlorine is in tap water
