Question

What is the symbol for cryoscopic constant?

Answer 1

Cryoscopic constant

• It is also known as Freezing Point Depression Constant or Molal Depression Constant.
• The symbol for cryoscopic constant is ${\mathit{\text{K}}}_{\text{f}}$.
• It depends on the nature of the solvents.

Relationship between cryoscopic constant and depression of freezing point

• The relationship between cryoscopic constant and depression of freezing point is as follows:-

$∆T_{\text{f}}=K_{\text{f}}\times \text{m}$

• Here, $∆T_{\text{f}}$ is the depression of the freezing point and $\text{m}$ is the molality of the solution.
