Salt (Sodium Chloride)

Not, its a homogeneous solution (a mixture).

Rock salt (halite) is impure sodium chloride (NaCl).

No. Osmosis will cause the red blood cells to release all of their moisture, and at the same time keep all of the materials INSIDE the cell wall. That's where the color comes from. If you use fresh water, or salt free water, osmosis will attempt to balance the salinity between the inside and outside of the cell resulting in cell rupture, called lysis. Salt water does not dry up the blood, it just makes it easier to clean.

When sodium chloride dissolves in water it does so because the positive and negative ions are attracted to the polar water molecules. Benzene molecules are not polar so there is much less attraction.

Sodium chloride is very soluble in water: approx. 360 g/L at 20 0C.

Salt in toothpaste is used as an abrasive. It's not nearly as effective as fighting off bacteria of the mouth as baking soda, but it still is proven to be effective. It will also fight off infections in your mouth.

Any chemical reaction occur.

Iodine itself is a deadly poison. In a "tincture of iodine" it was once used as a topical antibiotic, applied to cuts and scrapes. (It hurt like hell!)

Tiny amounts of iodine are essential to life; lack of sufficient iodine causes a disease called goiter. In the US, we prevent iodine deficiency by adding trace amounts of iodine to table salt. That's why most salt is called "iodized".

You need to know the molar mass of NaCl: 58,44 g.
If 3 kg of water contain 200 g NaCl, 1 kg contain 66,66 g.
58,44 g--------------------------1 mol
66,66 g--------------------------x
x = 66,66/58,49 = 1,14 mol

Yes, Benzoic acid is a weak acid (pKa ~ 4.2) that will dissolve in weak base such as sodium bicarbonate (pKa ~ 6.4)

Salt is added to foods as a preservative or to improve the taste.

"0.10 percent NaCl" is a concentration of sodium chloride in a solution. There are a lot of ways of expressing concentrations, but they all describe "how much of this" is in "how much of that." Percentages, such as yours, is commonly used in marketable goods, while chemists, and medical people use different ones.

0.10 percent NaCl means that for every liter of water, there is 1 gram of salt (1000:1 part ratio). That is not much: a pinch in a little more than a quart.

It reduces water activity which makes it difficult for pathogens to grow. Also, since fruits are generally sweet, the flavor profile is not significantly affected.

Sodium Chloride (NaCl=Salt) can be dissolved in water, so if NaCl mixes with silica, just put it in some water. (:

Sodium chloride at 801 0C is melted and at 1 413 0C become a gas.

250 g sodium chloride contain 99,16 g sodium.

It is a Ionic bond. Knowing that covalent bons only arise between non-metals. and Na(is a metal atom) and Cl forming together creates an Ionic bond which can arise between a non metal and a metal. Also, NaCl is a salt soluble in water (: where as silver chloride isn't I have noticed that question is fairly common among teachers (: answer with confidence!

Sodium chloride is an example of a common table salt.

This element is sodium (Na).

Yes, sodium ions and chloride ions move around seperatedly from each other, each of them are surrounded by 'hydrogen bonded' water molecules (approx. 20, mantled)

yep it also causes you to get scales on your bum, fangs and green and purple spotty wings. not nice angel wings though. More like....bats wings. but dont worry cos if that does happen at least you wont get any STD's cos no one will find you fit enough to sleep with you. however you may be taken to a secret government location and experimented on because some poor misguided fool has mistaken you for an alien. so anyway the moral of my story is dont eat too much salt. AND MAKE SURE YOUR FOOD ISNT FULL OF IT!!!

Yes because this is an ionic compound so when its dissovled in water the ions are free to conduct electricity

The impurities in sodium chloride are determined by different methods of analytical chemistry.

Salt - NaCl

Sodium Chloride is an elemental compound of Sodium and Chlorine.

However, in cooking, different variations of salts are used. It is not recommended to substitute one salt type for another, as the flavor and texture of your confection can be compromised.
