Question

Which one of the following aqueous solutions will have the highest boiling point? (a) 0.1 M urea (b) 30 g. of glucose per dm3 (c) 3.42 g. of sucrose in 100 ml (d) 0.2 M glucose

Answer 1

Answer:

(c) 3.42 g of sucrose in 100 ml

Answer 2

3.42 g. of sucrose in 100 ml

Explanation:

• The rise in the boiling point of the solution is a colligative property. i.e., an increase in solute particle concentration is proportional to an increase in boiling point.
• The temperature at which a liquid's vapour pressure matches the pressure surrounding it and the liquid transforms into a vapour is known as the boiling point of a material.

• The pressure in the environment has an impact on a liquid's boiling point.
• A liquid under a partial vacuum has a lower boiling point than a liquid at atmospheric pressure. At high pressure, a liquid's boiling point is higher than at atmospheric pressure.
• At sea level, water boils above 100 degrees Celsius (212 degrees Fahrenheit), while at 1,905 metres (6,250 feet), it boils at 93.4 degrees Celsius (200.1 degrees Fahrenheit).
• Depending on their pressure, various liquids boil at different temperatures.
