Salt molecules bond with water molecules, making it more difficult forr icce to form. The results is a lower freezing temperture. For example, a 10% salt solution freezes at 20'F (-6'C) , while a 20% salt solution freezes at 2'F (- 16'C).

∙ 13y agoAdding impurities to a compound generally lowers the melting point. Therefore, adding salt (an impurity) to water will lower its melting point to below OoC. Since melting and freezing points are identical, we expect water to freeze at a lower temperature. This is why salt is used in the winter on ice, if temperatures aren't too low, the salt will actually lower the melting point of the ice enough that it will melt, even at temperatures below zero.

Why do people use salt on icy roads?
because it will melt the ice on the sidewalks.
Why does salt melt ice the fastest?
salt water freezing temperatureWhen you place salt on the ice it starts to disolve making a saltwater solution .Salt water has a lower freezing point than water; therefore, the ice melts until the temperature of the water reaches the freezing temperature of salt water at that particular concentration.
Will bottled salt water placed into a bucket of water keep it from freezing?
It will certainly not keep the water in the bucket from freezing and, if the temperature goes low enough, the bottled salt water will also freeze.
Will 1 mol of sugar have the same effect as 1 mol of table salt in lowering the freezing point of water?
no because the mol of sugar is 34 g while salt's mol is 5.8 grams
Why does salt water freeze below 0 celsius?
Salt candissolve ice, so the salt in sea water act like a antifreeze. Sea Water would probably start freezing at - 15C
The process of what squeezes the salt out of salt water?
Freezing
What effect does salt have on the freezing pont of water?
It lowers the freezing point.
Why does salt effect the freezing point of water?
Salt mixes with the water raising it's freezing temperature above normal.
How does salt effect the properties of water?
Salt increases the boiling point of water and lowers its freezing point.
This process squeezes the salt out of salt water?
Evaporation, boiling or distillation will all result in separating the salt from the water.
What effect does chloride salt have on water temperature?
Sodium Chloride- table salt - lowers the water's boiling and freezing point.
What kind of salt to use on sidewalks for snow?
Salt works by lowering the melting or freezing point of water. The effect is termed 'freezing point depression'.
Why does salt melt ice faster than sugar or sand?
Salt. Salt dissolves in water, and causes the freezing point to fall; this causes the ice to melt. Sugar does not have this effect, and chalk doesn't dissolve in water.
How are boiling and freezing points of a sample of water affected when salt is dissolved in the water?
the freezing and boiling points rise significantly- this is why when you boil water in a saucepan, like for pasta, it is advised that you put salt in the water so that the water boils at a higher temperature, thus allowing you to heat the water to a higher temperature. hope this helps
What are the effect of impurities on the freezing point of water?
An impurity, such as salt lowers the freezing point of water by interfering with the lattice structure water makes with hydrogen bonding at it's freezing point.
Frozen salt water melt faster then frozen fresh water?
Salt lowers the melting or freezing point of water. The effect is termed 'freezing point depression'. Therefore frozen salt water melts faster and remain melted for long.
Does the amount of salt in water effect the rate at which water frezzes?
Yes, salt lowers the freezing point of water (makes it take longer to freeze)
