If a solution has a lot of particles, is it going to have a low or high boiling point? For instance, would NaCl have a higher or lower boiling point than C12H22O11, based on the amount of particles it has (NaCl has more than C12H22O11)?

Are you thinking of solutions with particles dissolved? If so, yes, the more particles, the lower the bp.

Yes, I am talking about dissolving particles. But in my book it says: "The higher the concentration of solute particles, the greater is the boiling-point elevation." Doesn't that imply that the more particles, the higher the bp?

You are correct, the bp is elevated, the freezing point is reduced. Sorry.

So more particles equals a higher boiling point and so sodium chloride would have a higher boiling point than sucrose and a lower freezing point. Is that correct?

for the same molality, yes.

yah thanks!

You're welcome! Just to clarify, when we're talking about solutions with dissolved particles, the boiling point elevation occurs. This means that the more solute particles there are in the solution, the higher the boiling point will be compared to the pure solvent. So, if we compare NaCl (sodium chloride) and C12H22O11 (sucrose), NaCl will have a higher boiling point because it has more dissolved particles compared to sucrose. Additionally, the freezing point of the solution would be lower compared to the freezing point of the pure solvent.
