Does Ice Melt Faster In Salt Water

When ice melts it takes energy heat from the surroundings.

Does ice melt faster in salt water. If there is less convection in saltwater then it will almost definitely take longer to melt the ice than freshwater. Salt slows down the freezing but not the melting. For example calcium chloride lowers the freezing point more than sodium chloride. Since the ice is artificially melting faster it takes more energy than normal lowering the surface temperature to below 0 degree c.

If there is more convection in salt water then the time to melt the ice may be closer or the saltwater may even melt it faster. This phenomenon is called freezing point depression. The ice cube in the salt water melts much slower then the one in the freshwater. It is true that an ice cube will melt much faster in tap water than in salt water.

In the salt water the colored water from the melted ice cube forms a distinct layer that floats on top of the salt water. Salt melts ice and help prevent re freezing by lowering the freezing point of water. As the ice cube melts the cold melt water from the ice cube sinks to the bottom of the cup forcing the water from the bottom of the cup ambient temperature to move toward the surface which transfers its heat to the ice cube causing it to melt faster. So ice melts faster.

In the fresh water the melted water sinks to the bottom and is evenly spread out.
