What is the effect on the boiling point of a solution (for example, water) produced by a soluble nonvolatile substance (for example, sodium chloride)? What is the effect of an insoluble substance such as sand or charcoal?

I believe if an insoluble substance is added, then the boiling point will remain the same because it does not affect the solution due to it not mixing and producing a new solution.

As for a soluble substance being added, I would think the boiling point would change since it would produce a new product or solution. Would it go up or down? i'm not sure

Any help would be appreciated, thanks!

adding a soluble substance raises the bp, and lowers the fp.

soluble and non-volatile impurity would have two effects on liquid whose boiling point is to be dteremined.

1.it affects the forces between the molecules.
2.it decreases the vapour pressure .thereby increases the boiling point if atm is high or decreases the boiling point if atm is low

When a soluble nonvolatile substance, such as sodium chloride, is added to a solution like water, it affects the boiling point of the solution. The effect is known as boiling point elevation.

1. Boiling Point Elevation: When a soluble nonvolatile substance is added to a solvent, it increases the boiling point of the solvent. This is because the added solute particles disrupt the solvent's vapor pressure, requiring a higher temperature to reach the boiling point. In the case of water with sodium chloride, the boiling point of the solution will be higher than the boiling point of pure water.

On the other hand, when an insoluble substance, such as sand or charcoal, is added to a solution, it does not dissolve or mix with the solvent. In this case:

2. No Effect on Boiling Point: Since the insoluble substance does not dissolve, it does not contribute any solute particles to the solution. Therefore, it does not affect the boiling point of the solution. In the example of sand or charcoal added to water, the boiling point of the solution will remain the same as that of pure water.

To summarize:

- Adding a soluble nonvolatile substance to a solution increases the boiling point, resulting in boiling point elevation.
- Adding an insoluble substance to a solution does not affect the boiling point.

I hope this helps clarify the effects of soluble and insoluble substances on the boiling point of a solution. Let me know if you need further assistance or have any more questions!

The effect of adding a soluble nonvolatile substance, like sodium chloride, to a solution, such as water, is an increase in the boiling point of the solution. This phenomenon is known as boiling point elevation. The reason behind this increase is that the presence of the solute particles (in this case, sodium chloride ions) disrupts the normal boiling process of the solvent (water molecules). It requires additional energy to break the solvent-solute attractions and convert the solution into vapor. As a result, more heat is needed to reach the boiling point and maintain the solution in the vapor state.

To determine the effect on the boiling point, you can use the equation:

ΔTb = Kbm

Where:
- ΔTb is the change in boiling point,
- Kb is the molal boiling point elevation constant, which is a characteristic property of the solvent,
- m is the molality of the solute, which represents the concentration of the solute in the solvent.

By knowing the molal boiling point elevation constant and the molality of the solute, you can calculate the change in boiling point. The value of Kb is specific to the solvent and can be found in reference materials.

On the other hand, if you add an insoluble substance like sand or charcoal, it does not dissolve or mix with water to form a new solution. Therefore, it does not affect the boiling point of the water. The sand or charcoal remains separate from the water, and their presence does not interfere with the boiling process. As a result, the boiling point of the water will remain the same.

In summary, adding a soluble nonvolatile substance to a solution increases its boiling point due to boiling point elevation. However, if you add an insoluble substance, such as sand or charcoal, it will not affect the boiling point of the solution as it remains separate and does not dissolve.
