Examples include salt in water, alcohol in water, or the mixing of two solids such as impurities in a finely powdered drug. In such cases, the added compound is the solute, and the original solid can be thought of as the solvent. The resulting solution or solid-solid mixture has a lower freezing point than the pure solvent or solid did. This phenomenon is what causes sea water, (a mixture of salt (and other things) in water) to remain liquid at temperatures below 0 °C (32 °F), the freezing point of pure water.

What is the relationship between freezing point depression and molar mass?
The relationship between freezing point depression and molar mass is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
What is the relationship between the molar mass and freezing point depression of a substance?
The relationship between the molar mass and freezing point depression of a substance is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
How can the freezing point depression method be used to calculate the molar mass of a solute in a solution?
The freezing point depression method can be used to calculate the molar mass of a solute in a solution by measuring the decrease in the freezing point of the solvent when the solute is added. By knowing the freezing point depression constant of the solvent and the amount of solute added, the molar mass of the solute can be calculated using the formula: molar mass (freezing point depression constant molality) / freezing point depression.
The depression of the freezing point is dependent on?
The depression of the freezing point is dependent on the concentration of solute particles in a solution. More solute particles lead to a greater depression of the freezing point.
What is the relationship between the molar mass and freezing point depression in lab answers?
The relationship between molar mass and freezing point depression in lab answers is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
Why does the freezing point decrease when naphthalene is added in camphor?
When naphthalene is added to camphor, it disrupts the crystalline structure of camphor by interfering with the intermolecular forces between camphor molecules. This disruption causes the camphor molecules to have a harder time coming together in an organized manner for freezing, resulting in a decrease in the freezing point.
The freezing point of a solution containing 4.12 g of unknown solute in 100 grams of camphor is 166.2 degrees C what is the freezing point depression?
The freezing point depression can be calculated using the formula: ΔTf = Kf * m, where ΔTf is the freezing point depression, Kf is the cryoscopic constant for the solvent (camphor), and m is the molality of the solution. Given that the freezing point of pure camphor is 178.4°C, the freezing point depression is 178.4°C - 166.2°C = 12.2°C. We need to first calculate the molality of the solution using the formula: molality (m) = moles of solute / kg of solvent. First, convert the mass of the solute (4.12 g) to moles, then calculate the molality. Once you have the molality, you can substitute it along with the freezing point depression into the formula to find the cryoscopic constant Kf.

What is the freezing point depression constant for water?
The freezing point depression constant for water is 1.86 degrees Celsius per molal.
How can one calculate freezing point depression in a solution?
To calculate freezing point depression in a solution, you can use the formula: Tf i Kf m. Tf represents the freezing point depression, i is the van't Hoff factor, Kf is the cryoscopic constant, and m is the molality of the solution. By plugging in these values, you can determine the freezing point depression of the solution.
