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.
