Plain water freezes quicker than salt water. Salt is a heating element, which is why it is often used to melt ice. This property causes water that has salt in it to freeze at a slower pace.
plain water, but the salt water will freeze colder
Pure water freeze faster.
Tap water.
Salt water will freeze faster because salt soaks in heat, making the water colder faster
plain water Salt lowers the freezing point of water.
The pure water freeze faster.
water freezes faster and only water freezes it takes AGES for salt water to freeze water takes about 4 hours in a freezer
Salt water does not freeze faster than pure water, and it freezes at a lower temperature. Salt is a form of anti-freeze, which is why it is put on roads in the winter, to help melt the snow.
Salt lowers the temp at which water freezes, that's all that happens. So it will defrost quicker, too.
Plain Tap water would freeze fastest.Adding salt or sugar to tap water will cause a depression/decrease in freezing point. Hence it will be harder to freeze the tap salt or sugar water.
Metal rust quickly in salt water than it does in pure water.
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.
