Molten-salt reactors are a type of nuclear reactor that uses molten salt(s) as a coolant or as a solvent in which the fissile material is dissolved. Experimental salts using lithium can be formed that have a melting point of 116 °C while still having a heat capacity of 1.54 J/(g·K). [4]
“When salt is added to this system, the ions in salt are attracted to the water molecules in [the surface semi-liquid layer],” Viswanathan says. “The ions on the surface of the salt get ...
The eutectic nature of salt and water is exploited when salt is spread on roads to aid snow removal, or mixed with ice to produce low temperatures (for example, in traditional ice cream making). Ethanol–water has an unusually biased eutectic point, i.e. it is close to pure ethanol, which sets the maximum proof obtainable by fractional freezing.
Next, mix one part water with one part vinegar and dip a soft cloth in the solution. Wipe the affected area until you see no sign of salt residue, and then use a clean cloth to dry the spot ...
When it snows, it pours – but why do municipalities treat the roads with salt? A chemist explains how salt affects water and ice. Salt doesn't melt ice – here's how it actually makes winter ...
The salt, via freezing point depression, helps melt the snow and ice and also gives vehicles more traction. Later, usually when the snow has ceased falling, snow plows, front end loaders with snowplow attachments, and graders cover every street pushing snow to the side of the road. Salt trucks often then return to deal with any remaining ice ...

The change in chemical potential of a solvent when a solute is added explains why boiling point elevation takes place. The boiling point elevation is a colligative property, which means that boiling point elevation is dependent on the number of dissolved particles and their number, but not their identity.
