Is ice made with salt water colder than ice made with pure water?

"Ice water" could either refer to water that has been chilled to the freezing temperature or just a container of water with ice floating in that is close to (but still above) that freezing temperature. Ice can be no warmer than the freezing point but can certainly be colder. If the solid (ice) is in equilibrium with the liquid ("ice water"), the ice will NOT be cooler, but as noted, if they are not really in equilibrium, you would expect the solid (ice) to be colder than the liquid water rather than the other way around.

∙ 13y agoWhat changes when you add salt to water is the freezing point. That is different than the temperature of ice. It is true that the freezing point of salty water is colder than the freezing point of pure water.
However, if you put an ice cube of pure water in a freezer at -100 °C, it will be colder than an ice cube of salty water in a freezer at -10 °C.
On the other hand, if both salty water and pure water were at 0 °C, then the pure water would be icy, and the salty water would be a liquid.
To find out how exactly how much the freezing point of water is affected by adding salt, see the Related Questions link to the left of this answer.
AnswerSalt itself cannot decrease the temperature of a block of ice. What salt does is lower the temperature water freezes at, so ice doesn't form until the temperature reaches the new, lower freezing point. This occurs because of the solution made when salt dissolves in water. The pure substance, water, has a freezing temperature of 32 degrees Fahrenheit (0 Celsius); any substance dissolved in it will lower its melting temperature by disrupting the forces the water molecules have on each other and lowering the stability of the ice crystal formed. Salt is used on roads because of its relatively low environmental impact and price. In addition, the salt molecule NaCl (sodium chloride) is ideal because it dissolves very well in water (35g/100ml at room temperature) and dissociates into two ions, doubling its effectiveness per gram. Real Answer:The above answer is incorrect. If you add salt to ice, it will cause the ice to melt. As it melts, a chemical exchange will occur that actually lowers the temperature of the "melt" (the water and ice solution) to below freezing (32° F). This is why you add salt to ice when making ice cream, so that the cream mixture freezes at a lower temperature.

Wiki User
∙ 13y agoThat depends on a lot of things however if you are talking about pure H20 in equal pressure environments then solid H20 (ice) will be colder than liquid H20 (water).

Wiki User
∙ 14y agoThey are the same thing cubes & blocks
Wiki User
∙ 14y agoNo, they are equal. Ice cold water can freeze things, and hot water can melt things, so no.

Wiki User
∙ 10y agoYes ice molecules are as a matter of fact colder than water molecules. When water cools to zero degrees Celsius, it becomes ice through freezing and the molecules become colder.

How do you think the melting point of salt water compares to that of pure water?
The melting point of salt water is even lower than pure water.
Are salt water pools colder than chlorine pools?
yes
What is the freezing point of sea water and pure water?
the sea water contains more salt. the pure water do not contain salt. the density of sea water is more than density of pure water. as there is more salt in sea water it is corrosive against the metals like aluminium. the pure water is not corrosive in nature. sea water is harmful for drinking. pure water is good for drinking.
Is seawater a pure substance or a mixture?
Seawater is a mixture. It is a combination of salt and water that is a homogeneous mixture. An example of a pure substance is either pure salt or pure sugar.
What is the problem for sugar and salt in the freezing point of water?
mixing of sugar and salt in water make a different solution . The freezing point of pure water and the solution is different due to the extra contents added in pure water.
Why is water made with salt water colder than water made with pure water?
Salt makes the water colder. Neither the question nor the answer make any sense. The question needs more context than it has. It sounds like you meant to ask something about the freezing point of water but you said 'water' not 'ice'. You don't tell us whether you started with two identical samples and added salt to one or whether two friends brought you samples of pure and salt water and you simply measured the temperature of both. One could easily make a counter-example by heating salt water and not heating pure water. The salt water will be warmer than the pure water.
Which is colder frozen water or frozen salt water at melting points?
The freezing point of salted water is lower compared with the freezing point of pure water. So when melting frozen salt water is colder.
Is salt water a pure substance and why?
no , its a mixture. salt is a pure substance, as is water, but togher they are a mixture.....
Is salt water colder then ice?
well for something to freeze it has to be 0 degrees or lower which is what ice is, frozen water. so the water has to be 1 degree or more to NOT freeze so the ice is colder than salt watercoz salt water is not frozen... does t6hat make sense? Actually, salt water CAN be colder than ice because the salt lowers the freezing point of the water.
Is salt water a mixture or a pure substance?
Salt water is definitely a mixture, a mixture of water and salt. It's not a pure substance because it's conformed of two components that aren't noticeable to the naked eye, but that can be easily separated.
Is NaHCO3 pure salt?
It is a pure salt, as it is made from an acid and a base.
What is the diff between salt and fresh water temperature?
Since the salt makes water boil, get colder, and melt faster, salt water would be warmer in the summer and colder in the winter, but the salt would help, but not 100%, keep the water from freezing.
How much water can salt have?
Pure and dried salt has no water.
How do you get pure water from a salt and water solution?
By evaporating the water of the solution and condensing it.
Is salt water colder than fresh water?
The freezing point of salted water is lower than the freezing point of pure water; this is a phenomenon known as freezing point depression when a solute exist in the solution.
Is a salt water a pure substances?
no, it's a mixture. Salt is a pure substance, as is water, but together they are a mixture.
Is salt water's density heavier than pure water?
Salt water's density greater (not heavier) than that of pure water.
