Does pure water freeze faster than regular water?

Answer 1

Yes pure (distilled) water will freeze faster than tap water because any impurities lower the freezing point. Regular water has minerals dissolved in it (such as calcium phosphate, and iron) and will freeze at a very slightly lower temperature than completely pure water.

Answer 2

The freezing point for pure water is 0 celsius (32 F). Anything that dissolves in water will make the water freeze at a lower temperature. What you might be noticing is the phenomenon called supercooling. If the temperature of pure water is lowered and there is no pattern for ice crystals to get together on, the water will not freeze until it is very cold...much lower than the freezing point. Impurities, like dust, sand and even scratches on the inside of the container 'remind' ice crystals how to form. It is sort of like a party...it is getting late and people want to sit down but there are no chairs.

Answer 3

The polyatomic ions that have disassociated themselves congruently throughout the homogeneous solution of the saline water causes a rapid coagulation of fission. It is this coagulated fission that appears to the naked eye as ice. Once examined further with an electron microscope it becomes apparrent that salt water actually does not freeze faster than pure water at all.

Answer 4

Pure water can freeze faster than regular water due to the absence of impurities. Impurities like minerals or contaminants in regular water can act as nucleation sites, making it slower to freeze compared to pure water. This phenomenon is known as the Mpemba effect.

Answer 5

as opposed to what? but usually plain water freezes slower than most things

Answer 6

haha i dunno :)

If you throw salt on an icy road it melts the ice so therefore water with salt in it would freeze a lot slower than pure water,

Answer 7

Spring water will freeze faster as it has more impurities in it, ice crystals form in the water around inpurties, therefore more impurties the quicker it will freeze
