First you need to know what a solute is, a solute is a minor part of a solution (the stuff dissolved in the solvent). That went from a solid into a liquid by a mixture Example, pouring salt into water. Next you need to know what solvent is, the liquid which a solute is dissolved in to form a solution, example water.

Now I'm going to explain how the solutes affect the freezing and boiling point of a solvent. Solutes increase the boiling point and solutes decrease the freezing point. solutes changes the boiling point of the solvent. when the solute is added in a solvent the boiling point of the solution increases. One example is, if salt is added to the water then the boiling point of water will increase to 100 degree Celsius. This happens because the boiling point is the temperature where the vapor pressure of the solvent becomes equal to the external atmospheric pressure. When solute is added in the solvent then solvent molecules take more time and temperature to make vapor pressure and causes the boiling point of the solvent increases.
Adding a solute to a solution decreases the freezing point, because it will interfere with the frozen solution's crystal structure. that means the temperature will have to be colder to overcome it and freeze the mixture anyway. A example, spraying salt or sand on an iced freeway in order to melt the ice. Mixing the salt decreases the freezing point so the snow will melt. Thank you for using my wiki.
