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.

Which would lower the freezing point more 100 moles of sugar or 100 moles of NaCl?
100 moles of NaCl
Can you lower freezing point of pure water?
The solution that will lower the freezing point of water the most is going to be the solution with the highest concentration of particles. This will likely depend on whether the salt dissociates into 2, 3, etc... particles.
How much would the freezing point of water decrease if 4 mol of NaCl were addes to 1 kg of water?
14.88 degrees Celsius.
Which has a lower freezing temperature 0.10 m NaCl or 0.10m glucose?
Glucose
Why does NaCl lower the freezing point of water by twice as much as sucrose?
If the solutions have the same molality, the salt will produce twice as many dissolved particles (Na+ ions and Cl- ions) but the sugar does not dissociate into particles when dissolved.
Will NaCl's affect the freezing point of a solution make the freezing point increase?
The freezing point of water solutions containing sodium chloride is lower.
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.
What happens when freezing H2O and NaCl?
The freezing point of the solution depends on the NaCl concentration.
Which would lower the freezing point more 100 moles of sugar or 100 moles of NaCl?
100 moles of NaCl
Which ionic compound will lower the freezing point the most of 1 mol of it is added to 1 mol of it is added to 1 L of water?
NaCl
Can regular salt melt ice?
Yes, salt can help melt ice by lowering the freezing point of water. When salt is applied to ice, it causes the ice to begin melting since the saltwater mixture has a lower freezing point than plain water.
How does NaCl melt ice?
Yes, because the heat of dissolution in water of NaCl is released and the freezing point of water lowered.
Why does an NaCl solution freeze at lower temperature than water but boils at higher temperature than water?
NaCl solution freezes at lower temp. than water but boils at higher temp.than water
What occurs when NaCl is added to water?
The boiling point of the solution increases, and the freezing point of the solution decreases.
Why is salt better than grit to melt ice?
when any substance is dissolved in water, it lowers the freezing point of the substance per concentration of solution. NaCl, commonly known as salt, dissolves very readily in water, lowering the freezing point and thus making water freeze at a lower temperature.
Can you lower freezing point of pure water?
The solution that will lower the freezing point of water the most is going to be the solution with the highest concentration of particles. This will likely depend on whether the salt dissociates into 2, 3, etc... particles.
What are the effects of impurities in boiling and freezing point?
Impurities lower the freezing point of a solution and raise the boiling point, a phenomenon known as freezing point depression and boiling point elevation. This occurs because impurities disrupt the crystal structure formed during freezing and reduce the vapor pressure during boiling, requiring higher or lower temperatures for the phase change to occur.
