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.

What is the pH of NACL solution?
NaCl is neutral so it will produce a solution with a pH of 7 in any concentration.
How do you detect sodium chloride solids in water?
Methods are:
- by determination of sodium
- by determination of chlorine
- using a salinometer
What are the functions of mineral salts in food?
There are many different functions of inorganic salts. Inorganic salts are used to preserve foods and dry out liquid substances for example.
1. The rock salt is grinded.
2. The grinded material is dissolved in water.
3. The liquid is filtered.
4. The solution containing sodium chloride is refinned by repeated processes of crystallization/recrystallization.
How do you prepare 50 ppm sodium from nacl?
Dissolve 50 mg NaCl pro analysis in 1 L demineralized water, at 20 0C, in a volumetric flask.
Why is there difference in conductivity between 5 percent NaCl solution and pure NaCl?
Pure solide NaCl is not electrically conductive.
The water solution of NaCl is an electrolyte and is conductive.
The common ion is chloride (Cl-).
How do you neutralize soil that has been saturated with salt?
Technically you do not "neutralize" salts in soils. What you want to do is dissolve and remove them.
For container plants, flush repeatedly with fresh clean water.
Considerable amounts of water are needed for flowerbeds, lawns, gardens or large plots of land in most parts of the world. Fields are normally irrigated with enough water to dissolve and wash the salts out of the root zone for the plants you are growing.
It is also very important to know whether any of the salts are sodium salts. If sodium salts are present (this is a saline-sodic soil) in a garden, yard or farm field, the sodium must first be displaced by another cation, like calcium, before flushing the soil with water. Gypsum is typically added to supply the calcium. If this is not done first, the soil structure will be ruined, and the field or garden will have to be flooded again after calcium is supplied to it, wasting time, money and soil productivity.
Another (longer term) idea...In Australia where there is a problem of sodic soils there are plantings of certain species that absorb the salt into their leaves to reduce the level in the soil. These can then be culled and the soil used. This may not be practical on a small scale though! Or if your in a hurry! The types of plants used are saltbushes, atriplex, myoporums, and some melaleucas although all countries have their own salt - tolerant species. Most are fast growing and small. In the meantime you could try growing asparagus... you are supposed to add salt when planting!How can you contrast sodium chloride and sucrose?

Is Sodium Chloride Polar Bond?
Sodium chloride exists as Na+ and Cl-. So it is ionic in solid state and in solutions and is polar.
Why does hot water dissolve more salt than cold water?
Salt dissolves quicker in hot water because the water molecules are moving faster than the cold water molecules, thus they have more contact with the salt molecules NaCl and break them up much faster.
How many ions are in 4.5 moles of NaCl?
4.5 moles NaCl = 4.5000000000001 formula units NaCl
*******************2nd Opinion*************
4.5 moles of NaCl would contain 4.5 x (6.02 x 1023) formula units.
= 2.7 x 1024 formula units
If you want to know how to remove salt from water, boil the water away and the salt will be left in the pan. OR, if its been sprinkled on a solid, take a spatula or spoon and scrape it off. Rinse it with a little cold water.
The two salts mainly used to put in food are potassium chloride and sodium chloride.
there are many different type of salts for example: the big cars that sprinkle salt on the road, salt in food, salt in the sea.etc
What are the major dissolved salts in oceans?
The Earth is composed of over 70 percent water. It is estimated that there are over 50 quadrillion tons of salt in the worldâ??s oceans.
What is the solubility of NaCl at 80 degrees Celsius?
Rising the temperature the solubility is increased but in the case of NaCl the effect is not so great.
How do you prepare sodium chloride 150 mM?
A (0,1 M)
1.Weigh 0,8766 g ultrapure NaCl dried at 110 0C for 30 min.
2. Transfer NaCl in a clean 150 mL volumetric flask using a funnel. 3. Wash the funnel with 120 mL demineralized water.
4. Put the flask in a thermostat and maintain 30 min at 20 0C.
5. Add demineralized water up to the mark.
6. Stir vigorously and transfer in a clean bottle with stopper.
7. Add a label with necessary information.B (0,2 M)

The four main types of salt-water bodies?
- Brackish water: 0,05-3 %
- Saline water: 3-5 %
- Brine: over 5 %
How much money was a pinch of salt?
a peck is a US standard dry measure equal to 8 quarts (US dry), or 1/4 bushel
a bushel (US) is 2150.42 cubic inches so a peck is 537.6 cubic inches
for salt this is about 22.4 pounds, or 37 1/4 cups (US fluid)
What mass of NaCl is required to dissolve 100 g NaCl to prepare a 1.50 m solution?
Remember the moles equations.
moles = mass(g) / Mr = [conc] x vol(mL) / 1000
Hence
mass(g) = [conc] x vol(mL) x Mr / 1000 (be algebraic rearragnement)
conc = 0.05 M
Mr = 23 + 35.5 = 58.5
vol(mL) = mass (g) = 150 g =150 mL (NB THis is the standard for water at STP)
Substituting
mas9g) = 0.05 x 58.5 x 150 / 1000
mass(g) = 0.43875 g ~ 0.44 g
