hot
Salt water exists over a wide range of temperatures; there is no required temperature. It is cold at the poles and warmer at the equator. It can freeze when it is cold enough, and you can boil it on the stove.
Salt lowers the freezing point of water, meaning it needs to be colder for the salt water to freeze compared to pure water. The salt itself does not freeze because its freezing temperature is much lower than that of the salt water solution.
If the salt is still in the water it will freeze inside the water so its technically frozen
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.
Pure water freeze faster.

Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
Any water that gets cold enough to freeze. You can freeze fresh water, brackish water, salt water, or polluted water.
The water that will freeze first is none because because sugar and salt are the same.They only have different taste.
Hot water with salt will freeze faster than cold water because the salt lowers the freezing point of water. This means that the hot water with salt will need to cool to a lower temperature before it can freeze, making the freezing process faster compared to cold water.

Salt water freezes before plain water because the presence of salt lowers the freezing point of the water. Cold water will freeze faster than hot water because the molecules in the cold water have less kinetic energy and are more likely to form solid ice structures.

It depends on how you're trying to freeze them, of course: if you have a freezer that goes to 0 degrees F, like the one in the back room of a supermarket, it'll take as long to freeze the salt water as it would plain water. (Salt water has a lower freezing temperature than plain water but if you have a cold-enough freezer, it'll freeze.) If you pour it into liquid nitrogen, it'll freeze instantly. It also depends on the temperature of the salt water at first. Also, which type of salt, and how pure the water is. It also depends on the concentration of salt.
