Question

State True or False.

All liquids boil at higher temperature than their normal boiling point when they contain non-volatile impurities.

• A. True
• B. False

Answer 1

The correct option is A True

The statement is true.
All liquids boil at a higher temperature than their normal boiling point when they contain non-volatile impurities. The degree of effect depending on the concentration of the impurities or other compounds. The presence of non-volatile impurities such as salts or compounds of a volatility far lower than the main component compound decreases its mole fraction and the solution's volatility, and thus raises the normal boiling point in proportion to the concentration of the solutes.
