Explain why a solution has a lower boiling point than the pure solvent?
Most solutions have a HIGHER boiling point than the pure solvent. A solution with a lower boiling point than the solvent has formed an azeotrope.
What is the boiling point of a 2.86 m solution of ammonium nitrate NH4NO3 Assume that the solvent is waterwhich has a Kb of 0.51ºCm and a boiling point of 100.0ºC?
102.9ºC
Why would the boiling point of a solution be higher than that of a pure solvent?
Liquids in a pure state have a specific boiling point.Water, for example, boils at 100 oC at 1 atm. However once there are impurities in the liquid the boiling point will be elevated. The degree of elevation depends on the quantity of impurity in the liquid.
How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
What is the boiling point of a 3.74 m solution of potassium perchlorate KClO4 Assume that the solvent is water which has a Kb of 0.51ºC m and a boiling point of 100.0ºC?
103.8 C

The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.
What is boiling out a solvent?
Boiling out a solvent is when you heat up a solution to a high enough temperature that the solvent (liquid) evaporates, leaving behind whatever you have dissolved.
What happens to a solvent when a nonvolatile solute is added to it?
It increases the boiling point of the solution and it increases the temperature range over which the solution remains a liquid.
How do you obtain a pure solvent from a solution by distillation?
By separating the mixture of solute and solvent based on their boiling points.
What happens to the boiling point of a solution as the concentraion increases?
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
How do different solutes affect boiling point?
When a solute is added to a solvent, the boiling point is raised according to the equation ΔTb=Kbm. Thus, the boiling temperature of a solution can be described by: Tb(solution)=ΔTb + Tb(pure solvent). However, for the purposes of this question, adding a solute increases the boiling point of a solution.
What is the boiling point of a 3.74 m solution of potassium perchlorate KClO4 Assume that the solvent is water which has a Kb of 0.51ºCm and a boiling point of 100.0ºC?
103.8c
What is the boiling point of a 2.35 m solution of sodium sulfate Na2SO4 Assume that the solvent is water which has a Kb of 0.51ºCm and a boiling point of 100.0ºC?
103.6ºC
What is the boiling point of a 2.86 m solution of ammonium nitrate NH4NO3 Assume that the solvent is waterwhich has a Kb of 0.51ºCm and a boiling point of 100.0ºC?
102.9ºC
A liquid with a solid dissolved in it is called a solution How might you get a solid back from a solution?
Boiling off the solvent to vapour if the solute is not too volatile.
Why would the boiling point of a solution be higher than that of a pure solvent?
Liquids in a pure state have a specific boiling point.Water, for example, boils at 100 oC at 1 atm. However once there are impurities in the liquid the boiling point will be elevated. The degree of elevation depends on the quantity of impurity in the liquid.
