The correct answer is false. Adding a solute to a solvent will not raise the freezing point of the solvent rather will lower it. This is because of the colligative property of the solution. When a solute is added to a solvent, some properties are affected and these set of properties are called colligative properties. The properties depend on the amount of solute dissolved in a solvent. These properties include freezing point depression, boiling point elevation, osmotic pressure and vapor pressure lowering.
