It is not a case of 'faster', but a difference in temperature.
Pure water at STP freezes at 0o C (zero degrees centigrade). This is the scientific standard.
However, If any substance is dissolved in water , this depress the freezing point.
So if there is fluoride in it the freezing point of 'fluoride water' will be lower than pure water.
Please see the Table of Cryoscopic Constants.
Sea water being saline, having sodium chloride dissolved in it , freezes when the water temperature reaches '-4oC' ( 27o F)
Yes, ammonium fluoride is soluble in water. It forms a colorless solution when dissolved in water.

To investigate whether hot water freezes faster than cold water, you would need two identical containers, water, a thermometer to measure the temperature of the water, a freezer to freeze the water, and a timer to track the freezing process. Ensure that you use the same amount of water in both containers and start with one container containing hot water and the other containing cold water at the same time.
Water freezes at 32 degrees Fahrenheit (0 degrees Celsius).
It is very cold water. At normal pressure, it is as cold as water can get before it starts to freeze.
Cold water freezes faster then warm water.
Cold water will freeze faster. Because the freezing point of water is 0oC, water that is closer to that point will freeze faster then hot water. This is because it will require less time to lower the temperature to the freezing point.
The process of water freezing into ice involves the temperature of water being lowered to 32 degrees Celsius. Hot water will take longer to freeze because the difference between the temperature of hot water and 32 degrees is greater than the temperature of cold water and 32 degrees.
Hot Water
the salt prevents the water from getting cold
Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.
Cold water. It doesn't have to cool as much as hot water does, thus it freezes faster. Under VERY specific labratory conditions, it can be made possible to have warmer water freeze faster, however, these conditions will not be present when you fill your ice tray. If you want ice, use cold water.
I believe hot water freezes faster because it is supercooled. Cold water is non-supercooled. When cold water freezes ice crystals form and float to the top, forming a layer of ice over the top of the water, so the layer of ice stops evaporation . While the hot water, which is probably no longer hot in the freezer,when it does freeze, it freezes throughout, creating more or less of a slush before freezing solid.
Cold water, less energy must be removed from cold water to make it freeze. warm water has more energy which needs to be removed before it freezes. it is an urban myth that warm water freezes faster.
cold liquids
A hypothesis for which freezes the fastest between cold and hot water could be that hot water freezes faster than cold water. This phenomenon, known as the Mpemba effect, has been observed under specific conditions where hot water cools faster than cold water due to factors such as evaporation and convection currents. This hypothesis would need to be tested through controlled experiments to draw a conclusion.
If you mean, compared with cold water, it doesn't. Hot water has to cool down first, before it freezes.
