Why heat is generated when ethanol is mixed with water? Please also explain why the existing hydrogen bond of water disintegrated to accommodate ethanol molecule?
sagarbhathwar said:Ethanol molecules are much smaller in size than the water molecules and as a consequence some of the ethanol molecules tend to cram in between the water molecules, thus breaking the hydrogen bond.
sagarbhathwar said:Enthalpy of mixing water and ethanol is -ve(exothermic), hence heat is liberated.
Mixing ethanol and water results in a solution with properties that differ from those of the individual components. This is because the molecules of ethanol and water interact with each other, forming new bonds and changing the overall properties of the solution.
The ratio of ethanol to water when mixing them can vary depending on the desired concentration of the solution. An example of a commonly used ratio is 70% ethanol and 30% water, which is often used as a disinfectant.
Yes, ethanol and water are completely miscible, meaning they can mix together in any proportion. This is because the molecules of ethanol and water have similar polarities and can form intermolecular bonds with each other.
If you mix equal parts of ethanol and water, you will get a solution with a concentration of approximately 50%. This solution is commonly used as a solvent and can also be used as a disinfectant.
Mixing ethanol and water has many uses. Some common ones include creating alcoholic beverages, as a disinfectant for cleaning and sanitizing, as a solvent for various substances, and as a fuel for vehicles and other machinery.
