Question

Rank the following aqueous solutions in order of increasing (c) freezing point;

Answer 1

0.01 m $AgNO_{3}$ < 0.03 m $CuSO_{4}$< 0.04 m urea

As molal concentration rises, so does freezing point depression. It can be expressed mathematically as ΔTf = Kfm.

What is Colligative Properties ?

• The concentration of solute particles in a solution, not the composition of the solute, determines a colligative properties .

• Osmotic pressure, boiling point elevation, freezing point depression, and vapor pressure reduction are examples of ligand-like properties.

What is freezing point depression?

• When less of another non-volatile material is added, the temperature at which a substance freezes decreases, a process known as Freezing-point depression.

• Examples include combining two solids together, such as contaminants in a finely powdered medicine, salt in water, alcohol in water.

• An significant factor in workplace safety is freezing points.
• If a substance is kept below its freezing point, it may become more or less dangerous.
• The freezing point additionally offers a crucial safety standard for evaluating the impacts of worker exposure to cold conditions.
