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?
Adding salt to water lowers the freezing point of the water. This is because the presence of salt disrupts the formation of ice crystals, making it harder for the water molecules to arrange into a solid structure at the same temperature as pure water.
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.
How much salt do you add to an ounce of water to keep it from freezing?
Just to be clear: adding salt, or anything else, to water will not "keep it from freezing". They just make it freeze at a lower temperature. The amount of salt you add depends on how much you need the freezing point to drop. If you just need to make sure it doesn't freeze at 0 degrees Celsius, then even a very small amount of salt will work. If you need it to stay liquid at -4 degrees Celsius, you're going to need to add a little over a mole of table salt per kilogram of water; a tenth of an ounce of salt per ounce of water should be more than sufficient. You can only dissolve about six moles of table salt per kilogram of water, which corresponds to a freezing point of around -23 degrees Celsius. If the temperature is going to be below that, no amount of salt will keep the water from freezing.
21.6 g NiSO4 in 1.00 102g Hu2082O what is the freezing point of this solution?
To determine the freezing point of the solution, you need to calculate the molality of the NiSO4 in the H2O solution. Once you have the molality, you can then use the formula for freezing point depression to find the freezing point. This formula is ΔTf = Kf * m, where ΔTf is the freezing point depression, Kf is the freezing point depression constant (for water it is 1.86 °C kg/mol), and m is the molality of the solution. Finally, add the freezing point depression to the normal freezing point of water (0°C) to find the freezing point of the solution.

How much salt is needed to stop 200ml of water freezing?
7 table spoons of salt stops 500ml of water from freezing
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.
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.
