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?
The ice cube made of salt and water will melt faster than the one made of sugar and water, which in turn will melt faster than the one made from just water. Salt and sugar lower the freezing point of water, which causes the ice to melt faster.
How long does it take to an ice cube with and without salt?
Adding salt to ice lowers its freezing point, which speeds up the melting process. This makes ice melt faster when salt is added compared to ice without salt. The exact time it takes for an ice cube to melt will depend on factors such as the amount of salt added, temperature, and size of the ice cube.
How long does a a 1inch cube of ice take to melt with one spoon of mineral rock salt?
The time it takes for a 1-inch cube of ice to melt with one spoon of mineral rock salt can vary depending on factors such as the temperature of the environment and the specific properties of the salt. In general, adding salt to ice lowers its freezing point, causing it to melt faster. It typically takes a few minutes for the ice cube to fully melt with the addition of salt.
How does the temperature affect ice melting with salt and sugar?
Both salt and sugar lower the freezing point of water, causing ice to melt at a lower temperature than it would in pure water. However, salt is more effective at lowering the freezing point than sugar, so it will melt ice faster at the same temperature. The presence of salt or sugar also disrupts the structure of the ice, further accelerating the melting process.
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?
Which ice cube will melt faster one made of salt and water another made of sugar and water or one made from just water?
The ice cube made of salt and water will melt faster than the one made of sugar and water, which in turn will melt faster than the one made from just water. Salt and sugar lower the freezing point of water, which causes the ice to melt 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.
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
Will flour water or salt water melt an ice cube faster?
Salt water will melt an ice cube faster than flour water. This is because salt lowers the freezing point of water, causing the ice to melt more quickly. Flour water does not lower the freezing point significantly, so it will melt ice at a slower rate.
Does salt or sugar melt faster?
Sugar melts faster than salt because sugar has a lower melting point than salt. Sugar typically begins to melt at around 320°F (160°C), whereas salt does not fully melt until it reaches temperatures exceeding 1,472°F (800°C).
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.
What makes ice cream melt faster than a ice cube?
salt
