Addding almost any impurity to water will lower the freezing point.
Adding a salt ( especially NaCl) is a popular way. Of all ways, adding anti-freeze which, is usually a glycol solution ( car radiator for example) is the way that is most often used worldwide.

∙ 15y agoAnything dissolved in water will lower the freezing point of the water. Alcohols such as propylene glycol and ethylene glycol are used as antifreeze in cars. They also elevate the boiling point and keep the car from boiling over when they get hot.

∙ 13y ago"Probably, by adding impurities like salts and all."
No, salts reduce the time it takes to evaporate. Quite the opposite.
You can:
a) lower the temperature
b) lower the pressure (Le Chatelier's Principle)
c) insulate (ie. styrofoam)

∙ 14y agoSurround the water with ice. I say surround it with ice because when ice is in your mouth, it melts a lot faster because of the 98.6 (avg.) temperature. So I figure that if you put water in a colder state, if it were just cold enough, it would solidify or freeze.
Or you could insert a wireless thermostat. :-) just kitting
Anyways, I figure that a freezer works somewhat like that too. I mean, there is ice on the walls. Of course, the water does not touch the ice, it just gets cold. Like REALLY cold.

How much salt is needed to stop 100ml of water freezing?
The freezing cannot be stopped; only the freezing temperature is lowered adding salts.
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 freezing temperature affect mocroorganisms and enzymes?
Freezing temperature make ice of the water in bacteria and completely stop there metabolic activity. Enzymes do not work at freezing temperature as they have no scope for movement in solid ice. So there activity halted.
What happens to the freezing point of pure water when salt is added to it?
it lowers it. impurities lower the melting and raise the boiling point of substances. they also cause the melting point to fall over a range now. for example, water's melting point was initially 0 but upon adding salt it now is -5 to -1 degrees celsius.
What type of change is freezing water?
Freezing water is an example of a physical change because the material contents of the water has not changed.
How do you stop water from freezing?
heat it up, add energy to it
What do you add to diesel to stop it freezing?
Anti gel at a truck stop...
What can you put in water to stop it from freezing?
SALT
How do you lower the freezing point into water?
Add salt.
Natural things to stop water freezing?
salt
How much salt is needed to stop 200ml of water freezing?
7 table spoons of salt stops 500ml of water from freezing
How much salt is needed to stop 100ml of water freezing?
The freezing cannot be stopped; only the freezing temperature is lowered adding salts.
The freezing point of water can be lowered by adding?
By adding any "foreign" molecules or ions. Such as if u add sugar or salt to water, it will lower the freezing point of water.
What happens if you mix salt with water?
The freezing point of the water is lowered. ADD: You get a salt water solution.
How do you stop water in birdbath from freezing?
Add 1 part rubbing alcohol to 4 parts water. The birds probably will be switching to snow or dirt baths during winter anyway, but if your birdbath has a pump, this mixture will prevent the water from freezing. This method also works in the windshield wiper fluid reservoir on a car.
If you add salt to water does it make freezing temperature higher or lower?
lower
How do you stop the water in a car from freezing?
In the winter, when the temps go below freezing, there should not be any water in a car. It should be antifreeze, actual windshield wiper fluid, etc.... This will prevent any freezing.
