Fresh water freezes at 0oC = 273 K
Salt water freezes at about -4oC = 269K
NB THere is a large body of chemistry dealing with cryoscopic constants; that is the depression of freezing point, between the pure substance and its dissolution .
Similarly, there are also Ebullioscopic Constants dealing the with rising of boiling points between pure substances and solutions.
Fresh water freezes faster than salt water because salt lowers the freezing point of water. When salt is dissolved in water, it disrupts the formation of ice crystals, requiring the salt water to become colder than fresh water in order to freeze. This phenomenon is known as the "freezing point depression."
Fresh water freezes at 32°f (0°c) at sea level. Sea water freezes at 28.4°f (-2°c) at sea level. Salt water depends on the concentration of salt. At maximum saturation salt water (23.3% by weight) freezes at -5.98°f (-21.1°c).
Fresh water will freeze faster than salt water, and at a higher temperature too. Why?Salt water is called salt water due to its containing dissolved salts -- usually Sodium Chloride (NaCl), but any other salts will do. When water freezes, the molecules link up into a crystal structure (ice). The atoms of any dissolved salts will interfere with the formation of the crystal, meaning more energy will have to be taken out (the temperature will have to drop lower) before salt water freezes.
Sugar water freezes faster than salt water. However, regular tap water will freeze faster than either salt, or sugar water.
Strong salt water freezes faster than weak salt water, as the added salt lowers the freezing point of the water. Therefore, strong salt water will reach freezing temperature quicker than weak salt water, coke, or Kool-Aid.
I think it is fresh water freezes faster because the salt melts ice.
Salt water freezes at a lower temperature than fresh water, so it typically takes longer for salt water to freeze compared to fresh water. This is because the presence of salt lowers the freezing point of water.
Fresh water
Fresh water freezes at a higher temperature than salt water. This is because the presence of impurities in water lowers its freezing point.

fresh water, because salt water is more dense
- Salt water is heavier than fresh water. - Fresh water freezes at zero degrees Celsius (32F), but salt water freezes at lower temperatures, depending on the amount of salt in the water. - Salt water boils at a higher temperature than fresh water.
salt water freezes at a lower temperature than fresh water so the fresh water gets frozen and not the salt water
Fresh water freezes at 32°f (0°c) at sea level. Sea water freezes at 28.4°f (-2°c) at sea level. Salt water depends on the concentration of salt. At maximum saturation salt water (23.3% by weight) freezes at -5.98°f (-21.1°c).
When it freezes, the salt remains behind in the sea.
