Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .

The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
As a reference, molten sodium chloride, table salt has a melting point ... 60:40 mixture of sodium nitrate and potassium nitrate is a liquid between 260–550 °C ...
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]
The most well-known of the twenty is certainly sodium chloride, otherwise known as common salt. All of the stable alkali metal halides have the formula MX where M is an alkali metal and X is a halogen. They are all white ionic crystalline solids that have high melting points.
WASHINGTON (Reuters) -U.S. government workers who have been buffeted by President Donald Trump's chaotic return to power face more uncertainty on Monday, when many of them will be required to ...
Sodium chlorate is an inorganic compound with the chemical formula Na ClO 3.It is a white crystalline powder that is readily soluble in water. It is hygroscopic.It decomposes above 300 °C to release oxygen [4] and leaves sodium chloride.
