Salt (Sodium Chloride)

Salt (NaCl) is made from sodium and chloride ions. Salt gives flavor to many meals. This compound is also in the form of a crystal lattice since it is made from two ions joining together.

The structural formula for sodium chloride?

See the Web Links to the left of this answer for diagrams of the structure. This structure is called the "NaCl Structure"! Several other ionic compounds have the same structure, but it is named after NaCl since that is such a common compound.

How do you find molar mass?

you need to find the relative atomic mass. without that, you can't find that information unless given to you. basically, molar mass is a mole. a huge unit, but if you have that one "mole" of hydrogen atoms, you will have a equivalent of 1 gram

The molar mass is the sum of the atomic weights of elements contained in the molecule, expressed in g/mole.

How did salt get in the ocean?

· 1. The most important part of the sodium and chlorine are dissolved from the earth salts and transported by rivers in seas/oceans.
2. A small part of chlorine is originated from the eruptions of submarine volcanoes.

white, small, granular, crystals, and salty it dissolves in water easily.

It is neither sour nor bitter

What is table salt?

Table salt is sodium chloride combined with iodine sources (for nutrition), stabilizers for the iodine, and anti-caking compounds to make it pour by preventing it from absorbing water from the air.
Sodium Chloride (NaCl).

Does salt dissolve in water?

Yes, salt is soluble in water and will dissolve to form a clear, salty solution. This is due to the polar nature of water molecules that allows them to surround and separate the ions in salt, breaking the ionic bonds and dissolving the salt.

What kind of mixture is table salt?

It is not a mixture; it is a compound. It is what's called an ionic compound, because the sodium atoms lose their 1 valence electron and the chlorine atoms pick up that electron to fill their outer energy level, giving them 8 valence electrons instead of 7 (7 is their normal number of valence electrons.)

The sodium atoms now have one less electron than protons, so they form a +1 ion and the chlorine atoms have one more electron than proton, so they form -1 ions. Since the ions have opposite charges, they are attracted to each other and form NaCl, or sodium chloride (table salt).

'fractional coordinates of Sodium Chloride?

The sodium ion is at 0,0,0 (symmetry related positions are 0,1/2,1/2; 1/2,0,1/2; 1/2,1/2,0).

The chloride is at 1/2,1/2,1/2 (symmetry related positions are 1/2,0,0; 0,1/2,0; 0,0,1/2).

For pictures, see e.g., http://webmineral.com/data/Halite.shtml

How does salt preserves food?

Bacteria dislike high concentrations of salt. There will be an osmotic imbalance. Water will escape the bactrim and enter the saline solution killing the bacteria. Has to be high levels of salt though.

What is a 12 GA superposed with a mild rust due to salt wood stock worth?

These "salt wood stock" guns are, depending on the extent of the damage, worth considerably less than an equal condition Superposed without the salt problem. There are a lot of variations of the Superposed that can also affect its value. My advice would be to consult one of the firearm pricing guides avalible at any large book store, keeping in mind that these pricing guides generally quote pricing that you might expcept to pay for the firearm at a gunshop not what they will give you for that gun.

What is a strong aqueous base?

A strong base is one that completely dissociates in water. Common examples are sodium hydroxide (NaOH) and postassium hydroxide (KOH). Both will fully dissociate into a metal ion (either Na+ or K+) and hydroxide ions (OH-). If you add a certain concentration of a strong base, the concentration of OH- in that solution is equal to the concentration of the base. This is not the case for weak acids, which do not dissociate completely. See the Web Links to the left of this answer for a complete list of the strong bases and more information.

Which has a higher freezing point calcium chloride or sodium chloride?

Answer: corrected CaCl2 melting point:

772 °C (anhydrous)

260 °C (monohydrate) 176 °C (dihydrate) 45.5 °C (tetrahydrate) 30 °C (hexahydrate)

NaCl melting point:

801 °C, 1074 K, 1474 °F

Calcium Chloride has a lower freezing point at -29 Deg F.

Sodium Chloride has a low limit of Approx -7De F

This couldn't be the right answer: these salts would have been molten to fluids at room temperature 68 oF !!

Why is the Salt Springs in the Ocala National Forest FL salty?

Water in the pool is very clear, blue, and is salty, the result of the water rising to the surface through ancient salt deposits. In places in the pool, there is a halocline visual distortion effect of salt and fresh water mixing. Fish, including striped bass, mullet, and small fry are abundant. In addition, blue crab and needlefish may be seen. The crabs are most commonly observed in the deeper portions of the spring openings. The marine life was established at the site millennia ago when this portion of Florida was part of a shallow sea. When the land rose upward, the marine creatures remained at the site because of the salty flow from the spring.

What is salt?

Salt is a mineral composed primarily of sodium chloride. It is commonly used as a seasoning in cooking to enhance flavor, as well as a preservative to extend the shelf life of food. Salt also plays a crucial role in maintaining proper fluid balance in the body.

How many grams of salt must be dissolved in water to make two liters of a two mole salt solution?

To make a two mole salt solution in two liters of water, you'll need 4 moles of salt (2 moles/L * 2 L = 4 moles). The molar mass of salt (NaCl) is approximately 58.44 g/mol, so 4 moles would be 233.76 grams (4 moles * 58.44 g/mol = 233.76 g).

Should you use food grade salt instead of rock salt and why or why not?

Rock salt is not as pure. There is often foreign material left from when they scraped it up from the ground. Food grade salt is much cleaner and it includs iodine which is there to prevent thyroid problems. You can still get coarse salt that is considered "food grade". If you are using it to melt snow use the rock salt its cheaper and the larger grains give better traction

How can you tell the difference between salt or sugar without tast?

There are two ways to tell the difference between salt and sugar without tasting either one of them. One way is to place them separately in separate pans, and cook them. Sugar has a higher boiling point than does salt. When heated sugar will melt into a brown syrupy sustains Salt will not melt. Another way is to pour them on a slug. Salt melts the skin of the slug, but sugar does not.

Why does salt improve your mood?

Salt has been shown to enhance the flavor of food, triggering the release of neurotransmitters such as dopamine in the brain which can improve mood. Additionally, consuming salt can help regulate the body's electrolyte balance which is important for overall health and well-being. However, it's important to consume salt in moderation as excessive intake can have negative effects on health.

How you can remove lithium chloride from water?

One way to remove lithium chloride from water is through a process called precipitation. By adding a chemical compound that can react with lithium chloride to form a solid precipitate, the lithium chloride can be removed by filtration or sedimentation. Another method is through reverse osmosis, where pressure is used to force water through a membrane that is impermeable to lithium chloride, thus separating it from the water.

How do we get salt from the earth?

Salt is mined in a process very similar to that of coal. Underground in a maze of networks. Look up Hutchinson KS. In that town there was a discovery of the largest deposit of salt in the U.S. It is 400 feet thick and spans across several states including Kansas, Oklahoma, Texas, and New Mexico.

Can you use Epsom salt in place of non-iodized salt?

These two salts are laxatives, but the Epsom salt is more frequently used.

Can you be allergic to sodium chloride?

I have a constant feeling of pressure in back of head and stuffy nose, one side then the other, when trying to sleep at night. After long trial and error I now think I might be allergic to sodium chloride? Could this be true?

How do you test the salt amount in water?

to test a salt shaker put rice in the shaker with the salt still in it. the rice keeps the salt moist and it keeps it from getting stuck in the shaker. Since the rice is big it will not fit through the holes so all you get out is salt.

A solution of sodium chloride in water is?

Sodium chloride dissolved in water form an electrolyte:

NaCl..............Na+ + Cl-
