What happens to the temperature of ice when you add salt to it?

It lowers the freezing point (makes it so it needs to be a lower temperature for the salt/water mixture to freeze).
This is called a "colligative property".
The salt molecules are not reacting with the water. In fact, colligative properties are based not on reactions or what you are adding, just how much stuff you are adding. For example, we could dump lots of sugar on the ice, and we would get the same effect (it would just be a lot more expensive!)
We can actually calculate how many degrees the salt will effect the freezing point of water by using the following equation: Delta T = - RM(T^2)m/Delta H

"Nothing. Salt in water lowers the freezing temperature."
"Nothing" - Not strictly true. In addition to lowering the Freezing point, the addition of salt weakens the hydrogen bonding that is responsible for waters high latent heat capacity. As you are not changing the energy of the system or the mass of water, you will get a net, if slight, increase in temperature in order to abide by the conservation of energy laws
This is more noticable when you dissolve other chemicals in water, such as concentrated Sulphuric Acid to water. You will get a noticable temperature rise. This is why you always add the acid the the water, and not the water to the acid, so if an accident does happen (like an explosion) it is going to be more diluted with adding the acid to the water. - Just a wee safety tip.
PS.OTAKUPS. I am answering his question on what happens to the temperature - it does increase! There's room for both our answers, regards, WEIRCHRI.

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.
What will happen if you add salt to ice?
It will reduce the cooling temperature and preserve the ice for longer period.
What happens if you add salt to water and ice?
The temperature drops below 0 degrees Celsius but the water doesn't freeze. another way to put it is that the ice doesn't melt as easily. The salt dissociates into sodium and chlorine ions Na+ Cl-
What in salt makes ice melt fastest?
"The ice cube without salt melts because the air around it is warmer than 32 degrees F. The salted cube melts faster. When you add salt it dissolves into the water of the ice cube. Salt water freezes at a lower temperature than the 32 degrees F at which freshwater freezes. The difference between the air temperature and the freezing point of salt water is bigger than the difference between the air temperature and the freezing point of freshwater. This makes the ice with salt on it melt faster." ("Salt and Ice." Salt and Ice. N.p., n.d. Web. 23 Nov. 2015.)
Which will melt first an ice cube or an ice cube with salt on it and why?
Ice cube with salt. The salt disrupts the lattice formation in the ice, lowering the melting temperature. As the salt melts ice, the surface area exposed to the salt increases, further perpetuationg the reaction.
Why happens when you add salt to very cold ice?
Salt release slowly the heat of dissolution and the temperature is increased.
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.

What will happen if you add salt to ice?

Do you add salt to the ice or the ice cream ingredients?
You add salt to ice to lower the temperature of the ice/water mixture. Without the salt, the temperature would not fall below 32.F, which is not cold enough 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 Salt causes water to freeze at a much lower temperature. Adding salt to the ice causes the temperature of the brine solution to drop dramatically, while freezing the ice cream inside the container.
Does the amount of salt you add to water effect the temperature of the melting point of the ice?
yes

What happens if you add ice to salt?
The ice will melt, as long as the temperature around it is over negative six degrees Fahrenheit. The salt combines with the snow, which is H2O, and creates salt water. Because the freezing point of salt water is negative six degrees, the salt shall melt if not in -6 degree weather.
Average temperature of soda?
The average temperature of soda is 66 F. This happens when you put it in ice, water, and salt.The average temperature of soda is 66 F. This happens when you put it in ice, water, and salt.
What happens when salt is added to ice?
If the ice is above a certain temperature, the salt will cause the ice to melt by lowering its melting point. The ice will absorb sensible heat as it melts, which means that the temperature of the solution will drop. If the temperature of the solution drops too low, the ice will stop melting unless it can absorb more heat from its surroundings.
How does salt cause the snow to melt?
Ice forms when the­ temperature of water reaches 0 degrees Celsius. When you add salt, that temperature drops. Addition of salt makes makes the melting point of ice increase, making the freezing point of water a lower temperature than just water along (i.e. without addition of salt). The salt dissolves into the liquid water in the ice and lowers its freezing point.
