There's nothing special about ice and salt; the freezing point of any substance lowers when you dissolve anything in it. This is called "freezing point depression" and it's one of the colligative properties of all substances.
"Why" is probably because the presence of the solute molecules interferes with the formation of the crystalline structure of the solid.

Does waters melting point increase when you add salt?
Nope. It decreases. By lowering the melting/freezing point of water, salt (usually in the form of rock salt) can be used to keep roads and other surfaces clear of ice, as it requires lower temperatures than normal to freeze.
How does adding salt affect the freezing point of water and what is the procedure of this experiment?
Adding salt (sodium chloride) the freezing point of water decrease; for an experiment add gradually salt (in known quantities) and measure the freezing point after each addition.
What happen to the temperature of ice when add some salt?
The salt does not alter the temperature of the snow, but gets into the structure of the ice crystals, causing the water (ice remember is frozen water and snow is ice) to have a lower freezing point.
When you make ice cream do you add salt to the ice or to the ice ingredients?
You add it to the ice used for cooling the mixture. It makes it colder. You don't want salt in what you eat!
What happens when you add salt to ice and why?
The freezing point of water decrease because the dissolution is a process which release heat.
When you add salt to ice what happens to the melting point of the ice?
Adding salt to ice decreases its melting point. Adding salt to the top of ice helps melt the ice faster.
Does the amount of salt you add to water effect the temperature of the melting point of the ice?
yes
How does one increase the melting or boiling point of a substance?
Add impurities (salt and others) to the substance.
What happens to the freezing point of pure water when salt is added to it?
it lowers it. impurities lower the melting and raise the boiling point of substances. they also cause the melting point to fall over a range now. for example, water's melting point was initially 0 but upon adding salt it now is -5 to -1 degrees celsius.
How the melting poinT OF Ice can be affected?
add some soluble impurity in water like salt etc.
Why goldsmith add borax to gold - option a increasing the melting point b decrease the melting point c elevate the boiling point d none of these?
D. So it has more mass so they can sell more of it.nothing to do with freezing or melting points.
Does waters melting point increase when you add salt?

Will more salt or less salt that will make the ice melt faster?
In theory, the more salt you add to ice, the more you lower its melting point and the more ice will melt.
What happens when you add salt to ice why?
The freezing point of water decrease because the dissolution is a process which release heat.

Adding salt (sodium chloride) the freezing point of water decrease; for an experiment add gradually salt (in known quantities) and measure the freezing point after each addition.
When you add salt to the ice will the ice remain constant or melt faster?
It will melt faster as the melting point of ice is higher than that of ice the salt with absorb the heat of the ice.
Does the melting point of water change?
Yes. The freezing point of water (melting point of ice) depends on both the temperature and the pressure. One easy way to lower the pressure is to add salt to ice. This lowers its freezing point and caused it to melt. Salt is spread on street and sidewalk ice in some areas to melt it and the addition of salt to ice is also used in the cooling of ice cream.
