As the number of solute particles in a given volume of solution increase will:
freezing point increase, vapor press decrease? or vice versa
or
boiling point increase, vapor pressure decrease? or vice versa?
Well, imagine you have a solution and suddenly a bunch of solute particles decide to have a party and join in. The freezing point would definitely increase because the solute particles would make it harder for the solvent particles to arrange themselves into a solid structure. So, freezing point goes up, just like costs at a fancy party.
Now, let's talk about vapor pressure. As the solute particles join the solution party, they start hogging some of that space that the solvent particles used to enjoy. This makes it more difficult for the solvent particles to escape the solution and turn into vapor, so the vapor pressure decreases. It's like adding more clowns to a tiny car - there's less room for everyone to breathe, so the pressure goes down.
Therefore, the answer is: as the number of solute particles in a given volume of solution increases, the freezing point increases, and the vapor pressure decreases. It's a party full of frozen clowns!
As the number of solute particles in a given volume of solution increases, two main effects can occur:
1. Freezing point: The freezing point of a solution is lower than that of the pure solvent. As the number of solute particles increases, the freezing point of the solution decreases. This is known as the colligative property of freezing point depression. So, in this case, the freezing point decreases rather than increases.
2. Vapor pressure: The vapor pressure of a solution is lower than that of the pure solvent. As the number of solute particles increases, the vapor pressure of the solution decreases. This is also a colligative property called vapor pressure depression. So, in this case, the vapor pressure decreases rather than increases.
To summarize:
- Freezing point: Decreases as the number of solute particles increases.
- Vapor pressure: Decreases as the number of solute particles increases.
The number of solute particles in a given volume of solution affects both the freezing point and the vapor pressure.
When the number of solute particles increases, the freezing point of the solution will decrease. This is because the solute particles interfere with the formation of the orderly arrangement of solvent particles during freezing, making it more difficult for the solvent to freeze.
On the other hand, as the number of solute particles increases, the vapor pressure of the solution will decrease. The presence of solute particles creates an obstruction to the solvent particles escaping from the liquid phase and entering the gas phase, resulting in a lower vapor pressure.
Therefore, as the number of solute particles in a given volume of solution increases, the freezing point will decrease, and the vapor pressure will also decrease.
Neither.
As # solute particles increases, freezing point decreases and vapor pressure decreases.
As # solute particles increase, vapor pressure gets smaller and boiling point gets larger.
I like this statement that summarizes it all.
As the number of solute particles increases, three things happen.
a. f.p is lowered.
b. b.p. is raised.
c. v.p. is lowered.
