If salt melts ice.....?

Salt doesn't melt ice, it reduces the temperature needed to melt it. In Antarctica the temperature is so low, that even all salt water around doesn't help melting it.

it's frostbite. the water melting off the ice cube is because salt lowers the freezing point and so the water on your skin is very cold <32 so it freezes the skin. kinda like making ice cream except more painfull

The salt cannot penetrate the ice crystall immedately

When any salt particularly NaCl is added to the ice, it lowers down the temperature. The FREE ENERGY of the ice is interfered by the energy due to the ions (Na+ and Cl-) of the salt added to it. The movement of water molecule is restricted to some extent in the ice in the presence of salts. The energy saved due to restriction of movement of water molecule is being utilised by the ice to remain at still lower termperature aganist the surrounding temperature. Thus addition of salt to ice reduces the ice temperature.

Interesting theory, however water expands when it freezes.  It has no problem melting under pressure.

The answer is either 0% or 100%. If ice is 0 degrees C it will remain as ice. [in theory]

Well your intuition here is correct. Just as ice cubes melting in water will not cause the glass to overflow, neither will metling icebergs (I assume you meant icebergs).\n\nBut as someone here pointed out, not all of the stored ice is floating about in the oceans, a lot of it is on land.When that ice melts and runs off into the oceans, the levels will rise.

My friend did one that answered the question : "Which melts ice faster: Salt or spices?"\n\nShe experimented with salt and spices like cinnimon, peprika, chili powder, red pepper...\n\nIt was pretty cool. The title we came up with was "Salt or Spice Melts the Ice?" \n\nSalt melted it the fastest.

Salt or calcium chloride sprinkled on ice will turn the water in ice to a liquid with a much lower freezing point, thus dissolving the ice.

Upon addition of salt to ice , it,s melting point increases and hence dissolves easily.

Simply put, the salt lowers the freezing point of water.\n\nHow does it do this?  From kinetic molecular theory, the temperature of an object is proportional to the random motion of the molecules of the object.  As water cools down the molecules move slower and stick closer together until the intermolecular forces are stong enough to lock the molecules into a crystal structure (overcome random motion) and water freezes.  The salt lowers these intermolecular forces by interacting with the water molecules: there is some salt-water interaction and thus less water-water interaction.  Thus, a lower temperature is required to lock in the crystal structure (lower melting point) and the ice melts.\n\nThis works to about -30 or -40 C IIRC.

You know that salt melts ice.\n\nDo a controlled experiment.  Set up four treatments using ice cubes in separate dishes.\n\n1: Ice alone.\n2: Ice + salt.\n3: Ice + sugar.\n4: Ice + flour.\n\nLook at the dishes every couple of minutes and write down what you see--which dishes have water and how much.  \n\nAfter a certain time, say 15 minutes or 30 minutes, remove the remaining ice (if there is any) and measure the amount of water that melted for each dish.\n\nRepeat the experiment at least one more time (more than one repeat is desirable).  \n\nPrepare a table that shows the results of your observations.  Look over the table and draw conclusions.

Because salt consists of sodium and chloride ions, and as You know, ions have charge, so You know there will be an interaction(attraction) between water molecules and the ions. You might also know that in ice, water molecules are in a definite distance from each other, they are in a crystal structure. Well, because of the interaction, that structure "opens up", and the water molecules get closer to each other, so the structure move from solid to liquid, as the interaction between them becomes weaker.\nI hope i was understandable. \nSalt lowers the boiling point and increases the freezing point of water. You can see it Yourself by putting salt into water, it'll boil sooner than without it.

When the ice was floating on water, the water had lifted by certain level..tht level was equal to the weight of the ice..s when the ice melts , the water level wont increase since the water from icemelt is equal to the earlier weight of the ice ...and the water on which ice was floating had already risen to accomadate tht weight..so it wont rise again when the ice melts...

Water/Ice changes state from solid to liquid when it's temperature rises or it's pressure rises.  So heating ice (obviously) melts it, and so does applying pressure (that's how an ice skate works; the pressure from the blade melts a thin layer of ice; the blade then "skates" on a thin layer of liquid water trapped in the ice grove.  This water soon re-freezes after the skater passes).  Of the two, applying heat is generally more effective then applying pressure.\n\nAnother method is to change the water/ice to something else that melts at a lower temperature.  Salt water has lower temperature freezing poing than pure water, so adding salt to ice can cause it to melt.  Ice cream freezers do this, and that's why salts (and similar chemicals) are put on frozen road surfaces.\n\nIn interesting way to heat a large area of ice outdoors is to put a dark coating over it.  Normally, ice reflects sunlight, so the sun does an inefficient job of heating and melting ice.  If you put black dust, dirt, paint, plastic, sand, or something else over it, then the black substance will absorb the sun's enegery and prevent it from being reflected away.  This trapped heat will then melt the ice much faster than if the sun were shinning directly on the ice.

Sea salt melts it quickly.\n\n\nPeace

b a solution, the salt will dissolve
