Soluble salts lower the freezing point of water due to bonds formed between
the ions and the water molecules. These bonds affect the formation of
ice crystals.

The nanofluid is a colloid, not a solution. The nanoparticles are suspended
in the water and minimally interact with the water molecules. Doesn't really
affect the freezing point.
