What is the fastest melting ice cream

The ice is in dynamic equilibrium with the liquid film on the surface. This liquid film is always reproduced.
Despite the cooling of the salt-water mixture wetting the ice, there is still enough energy available for new water molecules to be released from the crystal lattice of the ice. The water from the liquid film is "consumed" to dissolve the salt, but is therefore constantly replicated. The new, released water molecules release more ions from the salt. These in turn bind the water molecules. In order to maintain the equilibrium on the ice surface, a new film of liquid is created. The result: the ice slowly disappears.
In addition to the process of dissolving the salt, there is also the melting of the ice. Energy is required to dissolve the salt grid and to melt the ice. This is withdrawn from the environment in the form of heat. This lowers the temperature and the salt-water mixture cools down. Temperatures below 0 ° C are reached. During the dissolving process, salt cools the liquid or the ice-water-salt mixture.
The fact that the ice dissolves when salt is added is used for winter road clearance. By sprinkling with salt, roads that are as smooth as snow and ice can be made free of ice again.
Freezing point depression
The addition of salt to water has another consequence: the water molecules are prevented from building up an ice crystal at temperatures below 0 ° C. The salt solution only freezes at significantly lower temperatures, the freezing point of the water drops. Because the freezing point of a saline solution is -21.3 ° C, no more salt is scattered at lower temperatures - it would be ineffective.
