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 ice water with salt warmer or colder than plain ice water?
it is warmer
How can salt make ice colder and melt it?
Because of its chemicalsAnother AnswerSalt does not make ice 'colder'; salt melts ice by reducing its freezing point based on the mixture of salts with the ice/ water.
Can adding salt to ice water make it colder?
Adding salt to ice water does make it colder. It lowers the freezing point of the water making the mixture colder. The ice will melt more slowly because the water's freezing and melting points have been depressed by the addition of the solvent salt.
Why is salt water with ice colder than normal water with ice?
Because salt lowers the temperature of the water. It's a chemical reaction.
Why does adding salt to ice make ice colder?
Adding salt to ice water does make it colder. It lowers the freezing point of the water making the mixture colder. The ice will melt more slowly because the water's freezing and melting points have been depressed by the addition of the solvent salt. Adding the salt does not by itself lower the temperature of the water, it simply lowers the freezing point of the water.
Why would you add salt to ice water?
AnswerTo make it colder.
What causes salt to melt water?
Salt lowers the freezing temperature of water/ice therefore the water/ice needs to be colder then usual to freeze.
Which is colder dry ice or regular ice with salt?
Dry ice is colder
Why does salt make ice colder?
Salt doesn't make ice colder. It basically reduces the melting point of ice. Is an untrue answer, it melts the ice faster.
Why does water and ice cool the soda the fastest?
Because the salt lowers the freezing temperature of the water making the water colder. Ice in a glass of water will cool to 32 degrees. Ice with salt and water will cool to 25 degrees.
What is colder - ice or ice water?
I Know Snow is colder than Ice butt Ice Water is much colder than ice
Why do ice cream vendor sprinkle salt on the ice surrounding the ice cream cylinder?
It lowers the freezing temperature of the water/ice, causing it to become much colder and making colder/better ice cream.
Why does dry ice dissolve faster in salt water than water?
it is a process called freezing point depression. The salt lowers the freezing point of water therefore it has to be colder for the water to return to ice
How does salt cause ice cream to freeze?
Adding salt to ice make the ice colder thus the ice cream that's surrounded by the colder ice freezes better/quicker.
Is fresh water colder than salt water?
Salt water is colder than the fresh water.
Why is salt added to ice when you're making homemade ice cream in an ice freezer?
Salt has the effect of making the ice colder. Therefore, the ice cream becomes colder too. Salt is added to ice to lower the temperature of the ice/water mixture. Without the salt, the temperature would not fall below 0 degrees Celsius, which is needed to make ice cream. The freezing point of salt water is below that temperature and thus allows the cream to partially freeze, a necessary part of making ice cream.
When salt is added to an ice and water at 0 degrees celsius what happens?
Some Ice would melt, absorbing heat (enthalpy for the phase transition). Since Salt Water has a lower freezing point than zero degrees, the liquid will cool down. This colder liquid will chill the ice (if it isn't already colder than zero) and the result will be a mixture of ice and water that is colder than zero degrees C. This is why adding salt to ice buckets can cool Champagne faster.
What kind of salt would make ice water colder?
Any kind of salt will make some of the ice melt, and decrease the net temperature of the solute.
Why does water with salt take long to freeze?
Water with salt dissolved in it has to be colder than pure water in order to freeze. That's why we throw salt on snow and ice on the street to melt them.
Why do you add salt to the ice in an ice cream maker?
because salt makes stuff colder
What does adding salt do to making homemade ice cream?
Add salt to the ice to make it colder.
Can saltwater and freshwater freeze different or the same?
Salt water needs to be much colder than fresh water to freeze because salt melts ice.
Why does ice melt faster in tap water than in salt water?
When Salt dissolves into water it requires energy. Some energy is consumed by the process of salt dissolution and the water stays colder (relatively) for a longer time, thus it takes longer for the ice to melt.
Why does adding salt to water make it colder?
why does adding salt to water make it colder? The salt is not actually making the ice colder. The internal portions of the ice are already below 0 degrees Celsius. The salt, or NaCl, gets in the way of the intermolecular forces of the water, allowing the ice to melt at lower temperatures and remain in the water phase below 0. In other words, the water molecules are normally rigid enough to freeze at 0 degrees, but the addition of salt makes it more difficult for them to be rigid enough. This lowers the melting point. As the internal portions of the ice are already below 0, when the external ice is melted below 0 also, the internal, very cold portions, can further cool the water/ice mixture.
When making ice cream does the salt added to the ice make the ice cream freeze?
In a sense. When salt is added to ice the melting point is dropped, meaning that water and other things that freeze much be colder to freeze; this keeps the water that results in salty water at a colder temp--below the freezing point, so anything that is not salty that comes into contact with it freezes.
