Salt lowers the freezing point of water, causing the ice to melt at a lower temperature. When salt is sprinkled on ice, it disrupts the balance between solid and liquid states of water, leading to a net loss of energy, which ultimately makes the ice 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.
Salt lowers the freezing point of water, which means water can exist as a liquid at a colder temperature than 0 degrees Celsius. This colligative property makes possible the salting of roads up north so they don't freeze as easily, as well as churning home-made ice cream!

Salt does not make ice 'colder'; salt melts ice by reducing its freezing point based on the mixture of salts with the ice/ water.
salts absorb heat, that why the water become colder as it undergo endothermic reaction.
Any kind of salt will make some of the ice melt, and decrease the net temperature of the solute.
Adding salt to water creates a solution that has a lower freezing temperature than the ice cream mixture, bringing the temperature of the ice cream below its freezing point

Why ice don't melt in table salt?
It is because when you put in table salt, actually any salt, the ice absorbs the salt's energy and that is what make the ice colder than it was.
Why does the epsom salt melt the ice the slowest?
Epsom salt melts ice slowly because it has a lower freezing point compared to regular water, meaning it needs to be even colder to freeze. As a result, it takes longer for the ice to melt as the epsom salt absorbs heat from its surroundings to raise its temperature enough to melt the ice.
What happens when you put ice in salt water?
When you put ice in salt water, the salt lowers the freezing point of the water, causing the ice to melt. This process is known as freezing point depression. The ice absorbs heat from the surrounding water to melt, which makes the salt water colder than the original freshwater.
What doesn't melt ice?
colder temperatures then what the ice is, a working freezer
Does the salt melt ice faster if it can lower the freezing point more?
Yes, salt can melt ice faster by lowering the freezing point of water. When salt is added to ice, it disrupts the ability of water molecules to form solid ice crystals, causing the ice to melt at a lower temperature.
Why ice don't melt in table salt?
It is because when you put in table salt, actually any salt, the ice absorbs the salt's energy and that is what make the ice colder than it was.
Does higher concentration of salt in ice lower or raise the time at which it takes to melt?
Salt makes the ice colder, and the the ice would melt faster.
Would sugar work as well as salt when making ice cream?
For making the ice colder? It wouldn't work at all. The reason you put the salt on the ice is to make it melt; when ice melts it absorbs heat. Sugar won't melt ice.
What effect does salt water have on ice?
Fresh-water ice will melt faster in salt water than it will in fresh water or in the open air. Ice forms when water molecules are cooled down enough to arrange into solid crystals. Salt will, basically, get between the water molecules and make it harder for them to form crystals.
Will the amount of salt make a difference to melt ice?
Yes, the more salt the better to melt the ice.
What will happen if you add salt to ice?
Adding salt to ice lowers its freezing point, causing the ice to melt. This can create a brine solution that is colder than just ice, allowing it to absorb more heat from its surroundings. This is why salt is used to melt ice on roads or to make homemade ice cream.
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.
Does salt make ice melt?
Salt lowers the melting point of ice, making it melt faster and at a lower temperature.
Does salt make ice melt faster or does sugar?
Salt
Can salt make ice melt?
yes
What does adding salt do to making homemade ice cream?
Add salt to the ice to make it colder.
Why is salt added to ice?
To make it colder, faster.
