Will elevation in boiling point be same for 0.1 m NaCl and 0.1m sucrose solution?
No, the elevation in boiling point will not be the same for a 0.1 m NaCl solution and a 0.1 m sucrose solution. This is because the elevation in boiling point is directly proportional to the number of particles in the solution, known as the van't Hoff factor. NaCl dissociates into two ions (Na+ and Cl-) in solution, so it has a van't Hoff factor of 2, while sucrose does not dissociate and has a van't Hoff factor of 1. Therefore, the NaCl solution will have a greater elevation in boiling point compared to the sucrose solution.
Calculate the boiling temperature of a 0.50 M solution of sucrose. Assume that the concentration is 0.50 m.?
The boiling point elevation for sucrose (a non-electrolyte) is calculated using the formula ΔTb = i * Kb * m, where i is the Van't Hoff factor (1 for sucrose), Kb is the ebullioscopic constant for water (0.52°C/m), and m is the molality of the solution (0.50 m). Plugging in these values, we get ΔTb = 1 * 0.52 * 0.50 = 0.26°C. Therefore, the boiling temperature of the solution would be 100.26°C.
What is the van 't Hoff factor of sucrose and how does it affect colligative properties in solutions?
The van 't Hoff factor of sucrose is 1 because it does not dissociate in water. This means that sucrose does not affect colligative properties, such as boiling point elevation or freezing point depression, as much as substances that do dissociate into ions in solution.
How can one determine the boiling point of a solution?
The boiling point of a solution can be determined by measuring the temperature at which the solution changes from a liquid to a gas. This temperature is typically higher than the boiling point of the pure solvent due to the presence of solute particles in the solution.
What is the relationship between the sucrose van 't Hoff factor and colligative properties in solutions?
The sucrose van 't Hoff factor affects colligative properties in solutions by determining the number of particles that contribute to those properties. The van 't Hoff factor for sucrose is 1 because it does not dissociate into ions in solution, unlike salts that dissociate into multiple ions. This means that sucrose does not affect colligative properties as much as salts do, which can lower the freezing point and raise the boiling point of a solution.
Will elevation in boiling point be same for 0.1 m NaCl and 0.1m sucrose solution?
No, the elevation in boiling point will not be the same for a 0.1 m NaCl solution and a 0.1 m sucrose solution. This is because the elevation in boiling point is directly proportional to the number of particles in the solution, known as the van't Hoff factor.

Does sucrose have a high boiling point?
sucrose cannot boil, it caramelizes.
Calculate the boiling temperature of a 0.50 M solution of sucrose. Assume that the concentration is 0.50 m.?

What is the boiling point of water sucrose?
100
Why doesnt sucrose have a boiling listed?
Sucrose does not have a boiling point listed because it undergoes thermal decomposition before it reaches a boiling point. When heated, sucrose breaks down into its constituent molecules of glucose and fructose, along with other compounds. This decomposition process occurs before sucrose reaches a boiling point.
What is the van 't Hoff factor of sucrose and how does it affect colligative properties in solutions?
The van 't Hoff factor of sucrose is 1 because it does not dissociate in water. This means that sucrose does not affect colligative properties, such as boiling point elevation or freezing point depression, as much as substances that do dissociate into ions in solution.
What is the boilingpoint of sucrose?
Sucrose does not have a boiling point because it melts at 186 deg C and decomposes to form caramel.
The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.
The difference between the boiling point of a liquid in pure state and the boiling point of the liquid in solution?
Boiling Point Elevation
What is the boiling point of concentrated aqueous solution of sodium chloride?
The boiling point of a concentrated aqueous solution of sodium chloride is higher than that of pure water. This is due to the presence of the solute, which raises the boiling point of the solution through a process called boiling point elevation. The exact boiling point will depend on the concentration of the sodium chloride in the solution.
How can one determine the boiling point of a solution?
The boiling point of a solution can be determined by measuring the temperature at which the solution changes from a liquid to a gas. This temperature is typically higher than the boiling point of the pure solvent due to the presence of solute particles in the solution.
What is the boiling point of a 2.0 molal solution of glucose?
The boiling point is 101 oC.
