Assertion: The boiling point of a solution increases with increasing concentration of the solute.
Reasoning: The addition of a solute to a solvent increases the boiling point of the resulting solution due to the colligative property of boiling point elevation.
Both assertion and reasoning are true, and the reasoning is the correct explanation of the assertion.
Both assertion and reasoning are true, but the reasoning is not the correct explanation of the assertion.
Assertion is true, but reasoning is false.
Assertion is false, but reasoning is true.
The assertion is true because adding a solute to a solvent does indeed increase the boiling point of the resulting solution. This is due to the fact that the presence of solute particles in the solvent causes a decrease in the vapour pressure of the solvent, which in turn leads to an increase in the boiling point. The reasoning is the correct explanation of the assertion because the colligative property of boiling point elevation is responsible for this phenomenon.
