Does Ice Melt Faster In Salt Water

It is true that an ice cube will melt much faster in tap water than in salt water.

Does ice melt faster in salt water. 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. And although there is a difference in how high the ice cube will float in each as i d said before it is not enough to make the major difference. Salt slows down the freezing but not the melting. If there is less convection in saltwater then it will almost definitely take longer to melt the ice than freshwater.

Salt melts ice and help prevent re freezing by lowering the freezing point of water. In the fresh water the melted water sinks to the bottom and is evenly spread out. So ice melts faster. The working temperature range isn t the same for all types of salt.

Since the ice is artificially melting faster it takes more energy than normal lowering the surface temperature to below 0 degree c. When ice melts it takes energy heat from the surroundings. For example calcium chloride lowers the freezing point more than sodium chloride. 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.
