Assuming equal temperature, ice melts faster in salt water because salt water has a lower freezing point than fresh water, so the ice cube will have to absorb less heat in order to melt in salt water than in fresh water.

A deicer is a substance that melts or prevents the formation of ice, and does so by lowering the freezing point of water and preventing a bond between ice and paved surfaces.

Salt melts ice and helps keep water from re-freezing by lowering the freezing point of water. This phenomenon is called freezing point depression. Salt only helps if there is a little bit of liquid water available. The more particles (ions) formed when a salt dissolves, the more it lowers freezing point.

Because salt lowers the melting point of water, if you add salt to ice, the ice will melt. You might assume that, because the ice is melting faster, the salt has somehow heated up the ice faster than normal.

Salt will always melt ice quicker than both of them. This is because in the same amount or volume, there are more molecules of salt than sugar or baking soda due to the chemical make-up. Salt, baking soda, and sugar will all act to lower the freezing point of the ice, making it melt quicker than the untouched ice cube.

Hot or warm water is the most effective way to melt snow. Cover the puddle immediately after with a mix of salt and sand. This will prevent the melted snow (water) from being turned into ice. Use Ice Melter.

Use Hot Water Using hot water is probably the easiest way to melt snow. Spray hot water on the snow with a hose to melt it down. Note that it is not a long-lasting solution. This is why you need to cover the ground with sand or any ice-melter mixture to prevent the puddle from freezing.

Pouring hot water on an ice cube is a quick way to melt it. The hotter the water, the faster the ice cube will melt. You can boil the water in a pot and place the ice cube inside of it, or you can watch the ice cube melt slowly as you pour the water on it.
