Adding a solute to a solvent will increase its boiling point.
When a solute is added to a solvent, the solvent's molecules will need more time and higher temperature to make vapor pressure and reach its boiling point.
For example,
The boiling point of water (solvent) is 100°C. Add salt (solute) to the water and its new boiling point will become 102°C. Though the change is minimal, there is still change after adding a solute to a solvent.
