How can one determine the boiling point elevation of a solution?
The boiling point elevation of a solution can be determined by using the formula: Tb i Kf m, where Tb is the boiling point elevation, i is the van't Hoff factor, Kf is the cryoscopic constant, and m is the molality of the solution. By plugging in the values for these variables, one can calculate the boiling point elevation of the solution.
Calculate the boiling point of a solution of 10 grams of sodium chloride in 200 grams of water?
The boiling point elevation is determined by the molality of the solution, which can be calculated as the moles of solute divided by the mass of solvent in kg. From there, you can use the van't Hoff factor and the molal boiling point elevation constant to determine the change in boiling point. For sodium chloride, the van't Hoff factor is 2. The boiling point elevation constant for water is approximately 0.51 degrees Celsius/m.
What is the relationship between boiling point elevation and freezing point depression in a solution?
Boiling point elevation and freezing point depression are both colligative properties of a solution. Boiling point elevation occurs when the boiling point of a solvent increases when a solute is added, while freezing point depression happens when the freezing point of a solvent decreases with the addition of a solute. These phenomena are related because they both depend on the concentration of solute particles in the solution, with boiling point elevation and freezing point depression being proportional to the number of solute particles present.
How does the phenomenon of freezing point depression and boiling point elevation affect the properties of a solution?
Freezing point depression and boiling point elevation are both colligative properties that occur when solute particles are added to a solvent. Freezing point depression lowers the temperature at which a solution freezes, while boiling point elevation raises the temperature at which a solution boils. These changes in the freezing and boiling points affect the physical properties of the solution, making it different from the pure solvent.
What is the boiling and freezing point when it is 1.92 mole of naphthalene C10H8 in 16.8 mole of chloroform?
The boiling point elevation and freezing point depression of a solution are colligative properties that depend on the molality of the solute particles. Given the information provided, you would need the constants for the boiling point elevation and freezing point depression of the solvent (chloroform) to calculate the new boiling and freezing points.

What is the boiling point of a 2.35 m solution of sodium sulfate?
The boiling point of a solution increases with the concentration of solute particles. To calculate the boiling point elevation, you can use the formula: ΔTb = i * Kf * m, where i is the van't Hoff factor (2 for sodium sulfate), Kf is the ebullioscopic constant, and m is the molality of the solution. If you have these values, you can calculate the boiling point elevation using this formula.
What is the boiling point of an aqueous solution that has a vapor pressure of 18.5 at 25 degrees Celsius?

What is boiling point of 1 molar urea solution?
The boiling point of a 1 molar urea solution will be higher than the boiling point of pure water. Urea is a non-volatile solute that raises the boiling point of the solution through boiling point elevation. The exact boiling point elevation can be calculated using the formula: ΔTb = i * K_b * m, where i is the van't Hoff factor (1 for urea), K_b is the ebullioscopic constant of the solvent (water), and m is the molality of the solution.
What is the boiling point of a 2.47 molal solution of napthalene in benzenethe boiling point of benzene is 80.1?
To determine the boiling-point elevation of the solution, we need to use the formula: ΔTb = iKbm, where ΔTb is the boiling point elevation, i is the van't Hoff factor (for napthalene, i = 1 because it doesn't dissociate), Kb is the ebullioscopic constant of the solvent (benzene), and m is the molality of the solution (2.47 mol/kg). Plug in the values and solve for ΔTb. Add this value to the boiling point of benzene (80.1°C) to find the boiling point of the solution.
