Well. Bear with me here, this answer will be a little on the complicated side. The reason that solutes, like salt or sugar, melt ice is because of something called "freezing point depression" ... the salt (or sugar, or other solute) lowers the melting point of the ice. Freezing point depression is what physical chemists call a "colligative property." These doesn't depend on what the substance is, only how many dissolved "things" there are. Sugar is a covalent compound. It dissolves in water, but each sugar molecule produces only 1 "thing" ... the entire sugar molecule. Salt is an ionic compound. When it dissolves in water, for each formula unit 2 "things" are produced ... a sodium ion and a chloride ion. That means that sodium chloride is twice as effective per mole at lowering the freezing point of water as sugar is. How about by weight? A formula unit of sodium chloride is about 58.5 amu; a molecule of sugar ... well, there are lots of sugars; for simplicity's sake let's take table sugar with the formula C12H22O11. It's got a molecular weight of about 342 amu, nearly 6 times that of sodium chloride. Since sodium chloride is already twice as effective per mole, by weight it lowers the freezing point around 12 times as much as sugar does. This is one reason we use salt instead of sugar on our sidewalks in winter: it takes a lot less.
With salt because of the chemical salt has to make ice melt faster.
saltwater,cause the salt in the water will lower the freezing point
yes it does.. why do you think people put salt on ice outside when it snows
i think it is salt
sugar will melt the fastest
salt.
with salt
salt
Salt water cubes melt fast because the salt make it give up its BTUs faster
The salt will cause the ice to melt faster. the sugar shouldn't have much of a difference.
No. Salt water melts faster because salt makes the freezing point lower (meaning that it makes it less frozen and the temperature higher) so it can melt faster. Why do you think people put salt on the sidewalk when it snows?
It takes less time to melt the ice cube with salt.
Salt. Salt dissolves in water, and causes the freezing point to fall; this causes the ice to melt. Sugar does not have this effect, and chalk doesn't dissolve in water.
Salt water will melt an ice cube faster.
Salt would melt the ice cube faster because if you have noticed, people put down salt to melt the ice.
An ice cube melts faster in salt water.
Sugar. Salt often slows down the process of melting, so sugar is what would melt it faster.
Salt, obviously.
Salt water cubes melt fast because the salt make it give up its BTUs faster
yes.
Salt
sugar
When sugar is in water, it dissolves faster than salt does. I do not know the scientific reason why, but sugar melts faster.
salt
Yes it does, in northern states when it snows they use ice to melt the streets.
