Rank the following aqueous solutions in order of increasing<br> (c) freezing point;
saveliy_v [14]

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.

<h3>What is Colligative Properties ?</h3>
  • 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.
<h3>What is freezing point depression?</h3>
  • 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.
