Adding Salt to water will lower its melting point by about 5 degrees Centigrade. When it is cold outside, you spread salt over the roads so that even if the water is at -3 degrees, it will won't freeze.
When the salt is dissolved in water, it dissociates into the water and one tries to freeze the water, the salt alters the crystal structure, essentially lowering the melting point so the ice doesnt melt at 0 degrees, it melts at several degrees below zero. The crystal structure changes from H2O to NaCl-nH2O (n=hydration)
The amount of salt does affect the rate of melting. Salt normally raises the boiling point thus reduces melting rate.
Yes
Salt affects how fast ice melts in a cup of water. When you add salt, the melting process will be faster but it will only affect the part of the ice cube that comes into contact with salt.
Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.
salt lowers ice's melting point
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
nothing
Salt lower the freezing point of ice.
The salt will cause the ice to melt faster. the sugar shouldn't have much of a difference.

Salt lowers the melting point of ice.
Salt makes ice melt quicker and suger causes the ice to melt slower.
Ice melting in a glass, salt in the ocean
Adding salt to ice decreases its melting point. Adding salt to the top of ice helps melt the ice faster.

The melting point of ice decreases when salt is added.
Since impurities decrease melting point of solid ,so ice mixed with salt has lower melting point then pure ice .
Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.
