The freezing rate in order of fastest to slowest would be: tap water, bottled water and then salt water. Although it's a toss up between bottled water and tap water. The more sodium content of a solution, the slower the rate of freezing. In fact, a supersaterated sodium solution has to have a temperature of -21 degrees Celsius in order to freeze. Any temperature above that, will cause the salt to melt the ice. That is why they use use salt on icy roadways in the winter. If the ambient temperature is below -21 degrees celsius however, ice on the roads won't help. So salt water would be the last to freeze. Why did I say tap water before bottled water? Bottled water usually, but not always, comes from natural springs. Although some people prefer this water over tap water, spring water can contain minerals, such as sodium (salt), calcium, which can slow the rate of freezing, unless the temperature is low enough. Tap water is wastewater that has been treated with chemicals (such as chlorine) and and filtered prior to it being sent to your home. The addition of these chemicals shouldn't slow down the rate of freeze and that's why I said it's a toss up between bottled and tap water. The difference in chemical make-up shouldn't interfere with the freeze rate, especially in a home freezer. Note that water at room temperature tends to freeze slighlty faster then cold water in a home freezer.
It will certainly not keep the water in the bucket from freezing and, if the temperature goes low enough, the bottled salt water will also freeze.
Plain water because the salt in the other water lowers the freezing point. All molecules must line up in order to freeze, therefore if adding salt, the Na and CL must line up with the water molecules in order to freeze. With plain water, the molecules line up faster and thus freeze faster.
Assuming there are equal concentrations of salt and sugar in each sample, the sugar water will freeze faster. Salt dissociates into its ions when dissolved, giving two ions for ever salt molecule. Because freezing point depression depends only on concentration, and the concentration of ions is double that of the sugar, sugar will freeze faster.
Put both in the freezer and use a timer. It must be in a freezer, because if you have ever heard of super-cooled water, a lack of vibrations causes water to remain liquid below the normal freezing point (0 degrees Celsius), that is if it is not disturbed at all.
fresh water freezes at a higher temperature so should freeze before salt water. This is because when you dissolve substances in water you get freezing point depression this is where they need colder temperature to freeze. So this is why things like jam, vodka won't freeze in most home freezers even though they contain alot of water they also have alot of dissolved substances. Also why salt is spread on roads to melt the ice.
Water will freeze faster than salt water.
no salt water does not freeze faster than sugar.
Pure water freeze faster.
Salt water will.
It will certainly not keep the water in the bucket from freezing and, if the temperature goes low enough, the bottled salt water will also freeze.
weak salt water
Salt water does not freeze faster than regular water... When salt is put in water, it stops the water from freezing, and it needs to be colder than usual.
normal water with salt
Salt because water especially hot water will make it freeze faster.
It doesn't. Tap water freezes faster than salt water.
Fresh water freezes faster than salt water, yes.
Fresh water.
