Question

What is the standard state of ethanol?

Answer 1

Hint: In order to answer this question, to know the standard state of ethanol, first we should know the standard state of any material on what pressure. And then we will discuss the standard state of ethanol and we will discuss more about it.

Complete answer:
The standard state of ethanol is the liquid state.
The standard state of a material is its state at $ 1{\text{ }}bar{\text{ }}\left( {100{\text{ }}kPa} \right) $ .
The standard state can be defined at any temperature, but chemists generally use $ 25{\text{ }}^\circ C $.
Ethanol melts at $ - 114{\text{ }}^\circ C $ and boils at $ 78{\text{ }}^\circ C $, so ethanol is a liquid in its standard state.
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic chemical compound. It is a simple alcohol with the chemical formula $ {C_2}{H_6}O $. Its formula can be also written as $ C{H_3} - C{H_2} - OH$ or ${C_2}{H_5}OH $ (an ethyl group linked to a hydroxyl group), and is often abbreviated as $ EtOH $. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor. It is a psychoactive-substance, recreational drug, and the active ingredient in alcoholic drinks.
Ethanol is normally delivered by the maturation of sugars by yeasts or through petrochemical cycles like ethylene hydration. It has clinical applications as a clean and sanitizer. It is utilized as a substance dissolvable and in the union of natural mixtures. Ethanol is a fuel source.

Therefore, the standard state of ethanol is “Liquid”.

Note:
The standard state of a substance is its pure form at atmospheric pressure ( $ 1atm $ ) and the temperature of interest, which we usually choose to be $ 298{\text{ }}K{\text{ }}\left( {25^\circ C} \right) $. The standard enthalpy of a reaction is defined as the enthalpy change when all reactants and products are in their standard states.
