Do solutes increase or decrease the boiling point of a solvent?

No; solutes don't decrease the boiling point of the solvent, they increase it! Solutes decrease the melting point of the solvent! Think of it this way: low goes lower (melting point) and high goes higher (boiling point).

∙ 14y agoI wouldn't make any absolute statements about this, since there are many different kinds of solvents and many different kinds of solutes, however, there are certainly cases in which the boiling point increases, rather than decreases. The most familiar is the case of dissolving a salt (i.e., ionic compound) in water, which increases the boiling point and lowers the freezing point.

How does the boiling point of a solvent change when a solutes is dissolved in?
The boiling point rises and the freezing point lowers.The reason being, when a solute dissolves in a solvent, the solute molecules wedge themselves between the solvent molecules. In order for the solvent to freeze, its molecules have to get close enough together to form a solid. However, the solute molecules are in the way. As a result, it requires much colder temperatures for the solvent molecules to form a solid, despite the hindrance of the solute's molecules. The same sort of thing happens when trying to boil the solvent, only instead of holding the solvent molecules apart, the solute molecules end up holding them together, preventing them from boiling. Therefore, a more energy is needed to break the bond between solvent and solute, which allows the solvent to boil.
What effects do solutes have on a solvent's freezing and boiling boints?
The effect of a solute on the freezing point and boiling point of a solvent is related to what is known as the colligative property. Upon addition of the solute, the freezing point will be lowered, and the boiling point will be increased. The magnitude of the change will depend on the solute and how many particles it forms upon dissolving, and on the nature of the solvent and the freezing/boiling point constant for that solvent.
Which of these values is most responsible for changing the boiling and freezing points of a solvent?
Boiling point is dependent from pressure. Solutes also have a great impact on the freezing and boiling point.
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.
Which substance in the air is the solvent and which substances are the solutes?
Moisture in the air works as solvent and soluble substances present in the air are solutes.
Solutes decrease the boiling point of a solvent?
No: the boiling point is increased; see the link below.
What are two ways that solutes affect the properties of solvent?
Solutes lower the freezing point and raise the boiling point of a solvent! :)
Will the presence of a nonvolatile solute increase or decrease the boiling point of a solvent?
It will increase the boiling point of the solvent. In other words, it will take longer to boil. This is because the solute has intermolecular attractive forces with solvent making it more stable thus requiring more energy to overcome the attractions which is a higher temperature or boiling point.
How adding solute changes the properties of a solvent?
Solutes raise and lower the boiling points of solvents. :)

How can you change concentration?
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.

What is the solvent and solute of juice?
The solvent is water; but for solutes an infinite types exist.

What are the solutes in air and what are the solvents?
Solutes are substances dissolved in a solvent.
