In the technical terms of physical chemistry, the minimum freezing point of a water-salt mixture is −21.12 °C (−6.02 °F) for 23.31 wt% of salt. Freezing near this concentration is however so slow that the eutectic point of −22.4 °C (−8.3 °F) can be reached with about 25 wt% of salt.
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]

Trends in melting points can be even better explained when the structure and ionic size ratio is taken into account. [62] Above their melting point, salts melt and become molten salts (although some salts such as aluminium chloride and iron(III) chloride show molecule-like structures in the liquid phase). [63]
Both table salt and sea salt share a similar makeup, containing roughly 40 percent sodium by weight. One thing to be mindful of: Because table salt tends to be finer textured, the same volume of ...
Sodium chloride, also known as edible salt or table salt [87] (chemical formula NaCl), is the principal source of sodium (Na) in the diet, and is used as seasoning and preservative in such commodities as pickled preserves and jerky; for Americans, most sodium chloride comes from processed foods. [88]
Ice has a semi-liquid surface layer; When you mix salt onto that layer, it slowly lowers its melting point. The more surface area salt can cover, the better the chances for melting ice.
That’s about 1 teaspoon of table salt, or sodium chloride. But the average American consumes about 40% more, or 3,300 milligrams of sodium per day, ...
