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.

Which ice cube will melt faster one made of salt and water another made of sugar and water or one made from just water?
Salt water cubes melt fast because the salt make it give up its BTUs faster
How does the temperature affect ice melting with salt and sugar?
The salt will cause the ice to melt faster. the sugar shouldn't have much of a difference.
Will saltwater ice melt faster than freshwater ice?
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?
How long does it take to an ice cube with and without salt?
It takes less time to melt the ice cube with salt.
Why does salt melt ice faster than sugar or sand?
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.
Will flour water or salt water melt an ice cube faster?
Salt water will melt an ice cube faster.
What melts ice cubes faster sugar salt or food dye?
Salt would melt the ice cube faster because if you have noticed, people put down salt to melt the ice.
Does an ice cube melt faster in soapy or salt water?
An ice cube melts faster in salt water.
Does ice melt faster to salt or sugar?
Sugar. Salt often slows down the process of melting, so sugar is what would melt it faster.
What will make an ice cube melt salt or sugar?
Salt, obviously.
Which ice cube will melt faster one made of salt and water another made of sugar and water or one made from just water?
Salt water cubes melt fast because the salt make it give up its BTUs faster
Dose salt melt a ice cube faster?
yes.
Does salt make ice melt faster or does sugar?
Salt
Will ice melt faster with salt or sugar?
sugar
Does salt or sugar melt faster?
When sugar is in water, it dissolves faster than salt does. I do not know the scientific reason why, but sugar melts faster.
What makes ice melt faster sugar sandpepper or salt?
salt
Does an ice cube melt faster than an ice cube with salt?
Yes it does, in northern states when it snows they use ice to melt the streets.
