How is the freezing point of a solution defined?

Options

  1. AThe temperature at which the solid phase is in dynamic equilibrium with the liquid phase.
  2. BThe temperature at which the solid phase is in dynamic equilibrium with the gas phase.
  3. CThe temperature at which the liquid phase is in dynamic equilibrium with the gas phase.
  4. DThe temperature at which the vapour pressure of the substance is equal to the atmospheric pressure.

Correct answer

A. The temperature at which the solid phase is in dynamic equilibrium with the liquid phase.

Step-by-step solution

The freezing point of a substance is defined as the temperature at which the solid phase is in dynamic equilibrium with the liquid phase.
