Water becomes ice at a temperature of 32 degrees Fahrenheit (0 degrees Celsius), which we call the freezing point of water. Adding salt to water lowers the freezing point, thus preventing the formation of ice.
The primary difference between water and ice is the speed at which the molecules move. In water, the molecules move more rapidly than in ice. The temperature of the water is changed by adding or removing heat. As heat is removed, the water molecules slow down. At the freezing point, the motion of the molecules is slow enough that the water becomes ice.
When salt is added to water, the salt and water molecules stick together, <ore heat then must be removed to slow down and separate the combined salt and water molecules. The removal of the additional heat is required to freeze the salt-water combination. This means that the temperature at which it freezes is below that of pure water.
Antifreeze uses the same principle to keep the water in your car from freezing in the winter. Spreading salt over roads prevents melting snow from freezing into ice and causing hazardous road conditions.
For similar reasons, the addition of salt to water increases the boiling point of the water: more heat must be added to make the larger combined salt plus water molecule move fast enough to boil than must be added to make plain water boil. The result is that the temperature of the boiling salted water is higher than that of plain water.
Salt is not the only substance which lowers the freezing point of water. In fact, anything that can be dissolved in water will have the same effect.

Ice melts faster without salt than with salt because salt absorbs water therefore preventing ice with salt to melt quickly.
The freezing point of water is lower with added salts; the heat of solution is released.
Any impurity to a solvent raises its boiling point and decreases the freezing point, this is due to the lowering of the vapor pressure of the solvent.
Typically by adding salt to water it will raise its boiling point and lower its freezing point by 3-5 Degrees Celsius.
Salt lowers the freezing point of water from 32 degrees Fahrenheit (0 degrees Celsius) to 28 degrees Fahrenheit (-2 degrees Celsius). Similarly, salt also causes a suble change in the boiling point of water from 212 degrees Fahrenheit (100 degrees Celsius) to 212.5 degrees Fahrenheit (100.3 degrees Celsius).
yes they do melt faster like you know in the winter how you put salt out in the snow and it melts the snow,well that proves it
When you add a salt to ice , the salt lowers the freezing point of the water, keeping it from refreezing as easily and helping to melt the ice. In other word, the salt itself cannot melt ice. So if the Environment temperature is lower than the freezing point, the ice will not melt faster. But , if the temperature is higher than the freezing point, the salt will surely make the melting process faster .
The salt will cause the ice to melt faster. the sugar shouldn't have much of a difference.
AnswerSalt melts ice. Laundry detergent is like salt it lowers the melting temp and also creates traction
Theres NO chemcial in salt. Its regularly just melting....
Slower
Ice melts slower
Ice melt faster when: - the temperature is higher - powdered salts as sodium chloride or calcium chloride are added
yes. that's why they use salt as a de-icer on roads.

Salt water will melt an ice cube faster.
Salt makes Ice Melt Faster
it melts faster with salt
salt
Salt
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.
Paprika will NOT melt ice.
