The one that has the most particles or the most ions. For example, AlCl3 (4 ions) lowers freezing point more than CaCl2 (3 ions), which is better than NaCl (2 ions) which is better than glucose (1 particle).

When a solute dissolves into water the freezing point does what?
When a solute is dissolved into water the freezing point will lower. In other words, if you want to freeze a solution of water and some solute, you will have to cool it beyond the freezing point of pure water.
What is the molecular mass of 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 degrees C?
Calculate the molecular mass of the nonionic solutes. 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 ±C.
How does the presence of dissolved sodium chloride affect the boiling and freezing point of water?
Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.
Does solute effect the freezing point of water?
the temperature at which the solution freezes is lowered.
When urea is added to water the freezing point is decrease why?
This is a colligative property. Adding a solute will increase the boiling point and decrease the freezing point. The reason has to due with intermolecular forces, and interruption thereof. When water molecules have solute in between them, the temperature has to be lower than normal in order for them to freeze.

Why does the freezing point of water lower when solute is added?
the solute gets in the way of the water turning to ice
Is salt water colder than fresh water?
The freezing point of salted water is lower than the freezing point of pure water; this is a phenomenon known as freezing point depression when a solute exist in the solution.
What is the molecular mass of 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 degrees C?
Calculate the molecular mass of the nonionic solutes. 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 ±C.

How does solute lower freezing point of water?
One way is to physically impede the formation of the lattice structure of forming ice.
How does the presence of a solute affect the freezing and boiling points of a solvent?
They usually lower freezing points, think antifreeze. And salt water freezes at a lower temp than fresh, that is why they put salt on ice. And they raise boiling points, think salt in water when making spaghetti. Or, again antifreeze.
What is the Relationship of solute concentration and solvent concentration?
These words are the two parts of dissolution. A solute is what is being dissolved, and a solvent is what dissolves it. The most universal solvent is water, which means that most solutes can be dissolved into it. A solute (e.g. sugar) is dissolved in a solvent (e.g. water) to make a solution - sugar solution
How does NaCl lower the freezing point of water?
Any solute lowers the freezing point; there's nothing special about NaCl. One way to think about this is that the solute molecules "get in the way" of the freezing process: they don't fit into the regular crystalline lattice of the solid, which makes it harder to go from a liquid to a solid, which means the freezing point goes down.
Does adding a solute to a solvent raise the boiling point?
No, generally that would lower the freezing point, not raise it. Salty water freezes at a lower temperature than pure water. And salt can melt ice, which is the same phenomenon.
