Lowering the freezing point simply means that you have done something to whatever you want to freeze (or don't want to freeze), so that a lower temperature is needed to make it freeze.
For instance, adding salt to water lowers it's freezing point (which is normally 32 degrees Fahrenheit).
That's why salting a sidewalk or roadway makes the ice melt under normal winter conditions.
You can also lower the freezing point of water by adding alcohol or propylene glycol (automotive antifreeze).

When compared to pure water what will a 0.5 M solution of potassium chloride have a. lower boiling point b. lower freezing point c. higher capor pressure d. lower osmotic pressure?
a lower freezing point
Does salt affect the temperature of water -boiling point - freezing point?
i would opt for the Freezing point. salt decreases the freezing point of water. so if water would normally freeze at 0C, saltwater would freeze at -3C.
When comparing the freezing point and the boiling point of different substances the?
boiling point is always lower.
Does antifreeze have a lower or higher freezing point than water?
Much lower or else there would be little point in using as antifreeze
Does methanol lower the freezing point?
Methanol will freeze at negative 143 (Fahrenheit)/ negative 97 (Celsius). If it is added to water (freezing point of 32*F/0*C) then it will make the water freeze at a lower temperature. So yes, methanol will lower the freezing point of any liquid that freezes at a higher temperature than methanol. But methanol cannot lower the freezing point of any liquid that will still be liquid at -143*F/-97*C.
Is the freezing point of ice cream lower or higher than the freezing point of water?
It is lower.
Which has the lower freezing point oxygen or ethanol?
Oxygen has a lower point.
Which solutes will lower the freezing point of water the most?
Aluminum bromide (AlBr3) will lower the freezing point of water the most.
Can the freezing point be lower than its boiling point in a constant pressure?
At a constant pressure, the freezing point is always going to be lower than the boiling point.
If you add salt to water does it make the freezing temperature higher or lower?
It make the boiling point higher, and the freezing point lower.
How does the number of moles affect the freezing point?
Higher the concentration of the solute, lower is the freezing point.
What is the effect of salt in boiling and freezing temperatures?
The freezing point is lower and the boiling point is higher.
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.
Why is the curve for the freezing point of solvent different from the freezing point of solution?
it is increased with the increasing density
What causes a lower freezing point?
Salt.
When compared to pure water what will a 0.5 M solution of potassium chloride have a. lower boiling point b. lower freezing point c. higher capor pressure d. lower osmotic pressure?
a lower freezing point
Effects on freezing point when alum is dissolve in water?
The freezing point will be lower than water with nothing dissolved in it.
