The boiling point of 95% ethanol is higher than that of absolute ethanol

• a.) True
• b.) False

The statement is b.) False. The boiling point of absolute ethanol, which is 100% ethanol, is actually lower than that of 95% ethanol. This is because the presence of water in the 95% ethanol mixture raises its boiling point due to the formation of hydrogen bonds between water and ethanol molecules.

Key Points to Remember

• Absolute ethanol boils at approximately 78.37°C.
• 95% ethanol has a boiling point around 78.5°C.
• The addition of water affects the boiling point of ethanol mixtures.

Understanding the properties of ethanol mixtures is important in chemistry and various applications, such as distillation and fermentation.
