Table salt, or sodium chloride, has been used since antiquity.

The water contains a considerable percentage of common salt and other sodium salts and sulphur.

These results show that the composition of the salt, as anhydrous chlorides on a weight percentage basis, was calcium chloride ( CaCl < sub > 2 </ sub >) 14. 4 %, potassium chloride ( KCl ) 4. 4 %, magnesium chloride ( MgCl < sub > 2 </ sub >) 50. 8 % and sodium chloride ( common salt, NaCl ) 30. 4 %.

In comparison, the salt in the water of most oceans and seas is approximately 97 % sodium chloride.

When molten, the salt sodium chloride can be electrolyzed to yield metallic sodium and gaseous chlorine.

" It's typically a combination of salt and sodium nitrite, with the pink color added to distinguish it from ordinary salt.

Typical administration involves a pill or liquid containing sodium iodide ( NaI ) taken orally, which contains a small amount of iodine-131, amounting to perhaps less than a grain of salt.

For example, common table salt is sodium chloride.

Some structures are adopted by a number of compounds ; for example, the structure of the rock salt sodium chloride is also adopted by many alkali halides, and binary oxides such as MgO.

Today, the main ingredients of Marmite manufactured in the UK are glutamic acid-rich yeast extract, with lesser quantities of sodium chloride ( table salt ), vegetable extract, niacin, thiamine, spice extracts, riboflavin, folic acid, and celery extracts, although the precise composition is a trade secret.

* Sodium, a very common electrolyte ; not generally found in dietary supplements, despite being needed in large quantities, because the ion is very common in food: typically as sodium chloride, or common salt.

A big concern about the nutrition of potato chips is that because they are often made with salt, they may contain substantial levels of sodium.

However, it has been claimed that potato chips may actually contain less sodium / salt than the equivalent weight in corn flakes.

They combined their knowledge of pyroelectricity with their understanding of the underlying crystal structures that gave rise to pyroelectricity to predict crystal behavior, and demonstrated the effect using crystals of tourmaline, quartz, topaz, cane sugar, and Rochelle salt ( sodium potassium tartrate tetrahydrate ).

* Rock salt or halite, mineral form of sodium chloride

In 1 kg of rennet extract, there are about 0. 7 grams of active enzymes – the rest is water and salt and sometimes sodium benzoate, E211,

Many sodium compounds are useful, such as sodium hydroxide ( lye ) for soapmaking, and sodium chloride for use as a deicing agent and a nutrient ( edible salt ).

The sodium compounds that are the most important include table salt ( NaCl ), soda ash ( Na < sub > 2 </ sub > CO < sub > 3 </ sub >), baking soda ( NaHCO < sub > 3 </ sub >), caustic soda ( NaOH ), sodium nitrate ( NaNO < sub > 3 </ sub >), di-and tri-sodium phosphates, sodium thiosulfate ( Na < sub > 2 </ sub > S < sub > 2 </ sub > O < sub > 3 </ sub >· 5H < sub > 2 </ sub > O ), and borax ( Na < sub > 2 </ sub > B < sub > 4 </ sub > O < sub > 7 </ sub >· 10H < sub > 2 </ sub > O ).

Many popular vegetable juices, particularly ones with high tomato content, are high in sodium, and therefore consumption of them for health must be carefully considered.

Fat, carbohydrate and calorie content are low, with absence of vitamin C and sodium.

Salinity is the saltiness or dissolved salt content ( such as sodium chloride, magnesium and calcium sulfates, and bicarbonates ) of a body of water or in soil.

Vegemite contains 3. 45 % sodium, which equates to a salt content of approximately 8. 6 %.

** Phosphorylation of Na < sup >+</ sup >/ K < sup >+</ sup >- ATPase during the transport of sodium ( Na < sup >+</ sup >) and potassium ( K < sup >+</ sup >) ions across the cell membrane in osmoregulation to maintain homeostasis of the body's water content.

An indication of the minerals content is sodium (), potassium (), calcium (), magnesium ().

The sandwich has a high sodium and fat content, and has been specifically targeted by UK café chains in an effort to reduce salt and fat.

This is the only plant in the United States that produces Alberger salt, which is especially prized in the fast food industry because of its higher volume ( due to its unique shape ) and lower sodium content ( for a given volume, not weight ).

Hypervolemic hyponatremia-both sodium & water content increase, but the water gain is greater

Euvolemic hyponatremia-total body water increases, but the body's sodium content stays the same

Hot dogs often have high sodium, fat and nitrite content, ingredients linked to health problems.

Like many cured pork products, it is typically very high in sodium due to the salt content.

In passing through the ascending limb, the filtrate grows hypotonic since it has lost much of its sodium content.

Water should be low in iron and sodium, with a higher proportion of magnesium and calcium ions as part of its total mineral content.

According to The Mayo Clinic and Australian Professor Bruce Neal, the health consequences of ingesting sea salt or regular table salt are the same, as the content of sea salt is still mainly sodium chloride.

Healthy snacks include those that have significant vitamins, are low in saturated fat and added sugars and have a low sodium content.

Along the same proposed route, ranchers fear the effect of the proposed right of way upon their holdings in the Tongue River Valley, and the effect of newly developed strip mines and coalbed methane gas wells on the quality of water, since strip mines and coalbed methane wells can increase sodium content in surrounding water sources.

Research has also shown that pickle juice can be an effective remedy based on its high sodium and electrolyte content.

Potable water is available at Sidney Spit, but because of high sodium content it should not be consumed by those with heart or kidney ailments.

However, pork snacks are often very high in fat and sodium ; the fat content of pork rinds is similar to that of potato chips, but the amount of sodium in a serving of pork rinds is nearly five times that of a serving of potato chips.

The sodium content is 170mg.

In 1997, Lunchables came under fire for having high saturated fat and sodium content while being marketed as a healthy children's meal.

This is the only plant in the U. S. A. that produces Alberger salt, which is especially prized in the fast food industry because of its higher volume ( due to its unique shape ) and lower sodium content ( for a given volume, not weight ).
