Salt equivalent is usually quoted on food nutrition information tables on food labels, and is a different way of defining sodium intake, noting that salt is chemically sodium chloride. To convert from sodium to the approximate salt equivalent, multiply sodium content by 2.5:
The compressibility of a salt is strongly determined by its structure, and in particular the coordination number. For example, halides with the caesium chloride structure (coordination number 8) are less compressible than those with the sodium chloride structure (coordination number 6), and less again than those with a coordination number of 4 ...
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 .
Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including humans. Sodium is an essential element for all animals and some plants.
While reduction of sodium intake to less than 2,300 mg per day is recommended by developed countries, [9] one review recommended that sodium intake be reduced to at least 1,200 mg (contained in 3 g of salt) per day, as a further reduction in salt intake led to a greater fall in systolic blood pressure for all age groups and ethnicities.

Sodium malate is salty in taste and may be blended with other salt substitutes. Although it contains sodium, the mass fraction is lower. [17] Monosodium glutamate is often used as a substitute for salt in processed and restaurant food, due to its salty taste and low sodium content compared to table salt, and can also be used effectively in home ...
Sodium salts are salts composed of a sodium cation and any anion. The anion may be the conjugate base of some inorganic or organic acids , or any monatomic or polyatomic anion . They can be formed by the neutralization of acids with sodium hydroxide .
In 1910, the colony became a province of the Union of South Africa and in 1961 of the Republic of South Africa. When the homeland of KwaZulu, which means "Place of the Zulu" was re-incorporated into the Natal province after the end of apartheid in 1994, the province of Natal, which had existed between 1910 and 1994, was renamed KwaZulu-Natal.
