DID YOU KNOW......
Salt is paradoxical,the bible lists nearly 50 references to salt.Many of them positive references,such as the requirements of adding salt to a grain offering (Leviticus 2:13).Yet in our contemporary culture,salt is a generally regarded as a health-robbing food additive linked to cardiovascular and other diseases.Ever wondered why salt is tasty,why we need it in our body and its important ingredient in our daily food...well we got something for you....
Salt consists of 40% sodium and 60% chloride joined tofether chemically to make a compound.Salt is a dietary mineral composed of sodium chloride that is important for animal life, and dangerous to many land plants.Salt flavor is one of preservation.Salt for human consumption is produced in different forms such as:unrefined salt (such as sea salt),refined salt (table salt),and iodized salt.Chloride of all known creatures,including humans.Salt is involved in regulating the water content (fluid balance) of the body.Over consumption of salt increases the risk of health problems,including high blood pressure.
CHEMICAL NAME.....
The chemical name for table salt is sodium chloride.It is written ‘NaCl’.Na+1 is sodium, and Cl-1 is chloride,the formula for salt is NaCl.The salt that we eat is called sodium chloride also known as salt,common salt,table salt or halite which is an ionic compound with the formula NaCl.
SALT AND OUR BODIES
Our body have 68% of water , salt helps us without reducing water content in our body. It helps to digest food,stomach nerves will generate some acids.Due to this acids we may get pain,stones and we will feel like burning.The salt which is present in between the nerve cells helps us to save from pain,stones and burning sensation. After eating food it should digest,while digestion salt helps in removing waste materials from our body.Like this salt plays an important role in digestion process. To get bone power salt plays a dominant role.
If our bodies should operate well salt’s use is immense. Thus, salt have all the above importance’s,suppose if a certain amount of salt content is not present in our body there may be a chance.
TIPS FOR YOU....
Most foods that we cook at home do not need salt as they already have salt in them,and we also do not need a salt shaker on the table to add even more salt...you will find that food still tastes good.
Fast-foods,snacks,processed foods,canned,packet foods such as biscuits, potato crisps and corn chips have a lot of salt in them. Look for salt in soups,pasta meals,pizza, take-away meals,mayo,ketchup.chips,biscuits and cakes.Taste your food before adding salt or sauce.
You will problably find you do not need to add salt.
Have less salty snacks,bacon,cheese,pickles
and smoked fish.
It used as a bathing solvent scrub with it when bathing to smoothen your skin. Salt is used to clean teeth.It also helps either to improve cleaning,and provide a medical improvement in our bodies.
Not only humans even animals need salt to help their bodies work well. Often farmers, or hunters, will make a salt lick so the animals can get the salt that they need. They really like salt so that's why hunters may use a salt lick to attract animals to that area.
EFFECTS OF SALT IN OUR BODY
Many people consume excessive amounts of salt, also known as sodium, on a daily basis without knowing the potential health risks associated with salt intake.
Sodium is one of the primary electrolytes in the body.All four cationic electrolytes (sodium,potassium,magnesium and calcium) are available in unrefined salt,as are other vital minerals for optimal bodily function.Too much or too little salt in the diet lead to muscle dizziness or electrolyte disturbance,which can cause neurological problems or being fatal.Drinking too much water with insufficient salt intake puts a person at risks of water intoxication(hyponatremia).
Salt has been important to humans throughout history
Salt is used to help make food last longer. Many foods have been to the cities and towns of that time. Long time ago people would boil seawater in a clay pot then collect the salt which was left when the water had boiled away. It was a long slow job to get little salt. In some very poor countries people are still forced to get their salt this way. Some people believe that salt can protect against demons. Some people believe that using salt can purify people and objects - that is free them from evil. A Bible story tells of Lot's wife who was turned into a pillar of salt because she disobeyed God. Some people believe that the large pillar of rock-salt which stands today on Mount Sodom is Lot's wife. pickled in brine (salty water) had a lot of salt rubbed them to make the food last longer. Salt was so important to keep food safe in the Middle Ages that special salt roads were built to get salt from ports.

Soap is an anionic surfactant used in conjunction with water for washing and cleaning which historically comes either in solid bars or in the form of a viscous liquid. The use of soap has become universal in industrialized nations due to a better understanding of the role of hygiene in reducing the population size of pathogenic microorganisms
HOW IS SOAP FORMED
Soap consists of sodium or pottasium salts of fatty acids and is obtained by reacting common oils or fats with a strong alkaline solution.Saponification of fats and oils is the most widely used soap making process.This method involves heating fats and oils and reacting them with a liquid alkali to produce soap and water plus glycerine.
Fatty acid (oil) + Base (lye) = “A Salt” (soap)
The oil or fat is heated gently. Lye and water are combined separately. When both ingredients reach the required temperature, they are combined. When the mixture becomes the desired consistency, it is poured into a mould. The bars are then removed from the mould after setting up. The other method of soap making is the cold process method, where fats such as olive oil react withlye, while some soapers use the historical hot process. In both cold-process and hot-process soapmaking, heat may be required for saponification.
The main benefit of hot processing is that the exact concentration of the lye solution does not need to be known to perform the process with adequate success. Unlike cold-processed soap, hot-processed soap can be used right away because lye and fat saponify more quickly at the higher temperatures used in hot-process soapmaking.
In the hot-process method, lye and fat are boiled together at 80–100 °C until saponification occurs, which the soapmaker can determine by taste,the bright, distinctive taste of lye disappears once all the lye is saponified or by eye ,the experienced eye can tell when gel stage and full saponification have occurred. After saponification has occurred, the soap is sometimes precipitated from the solution by adding salt, and the excess liquid drained off. The hot, soft soap is then spooned into a mold.
Cold-process soapmaking requires exact measurements of lye and fat amounts and computing their ratio, using saponification charts to ensure that the finished product is mild and skin-friendly.Cold-process soapmaking takes place at a sufficient temperature to ensure the liquidification of the fat being used. The lye and fat may be kept warm after mixing to ensure that the soap is completely saponified.
STRUCTURE OF SOAP
The common process of purifying soap involves removal of sodium chloride,sodium hydroxide,glycerol and some impurities. These components are removed by boiling the crude soapcurds in water and re-precipitating the soap with salt.
USES OF SOAP
Soaps are useful for cleaning because soap molecules have both ahydrophilic end,which dissolves in water, as well as a hydrophobic end, which is able to dissolve nonpolar grease molecules. Although grease will normally adhere to skin or clothing, the soap molecules can form micelles which surround the grease particles and allow them to be dissolved in water. Applied to a soiled surface, soapy water effectively holds particles in colloidal suspension so it can be rinsed off with clean water. The hydrophobic portion dissolves dirt and oils, while the ionic end dissolves in water. Therefore, it allows water to remove normally-insoluble matter by emulsification.In other words, while normally oil and water do not mix, the addition of soap allows oils to dissolve in water, allowing them to be rinsed away.
MICELLES IN WATER
The cleansing action of soap is determined by its polar and non-polar structures in conjunction with an application of solubility principles. The long hydrocarbon chain is of course non-polar and hydrophobic (repelled by water). The "salt" end of the soap molecule is ionic and hydrophilic (water soluble).
When soap is added to water, the ionic-salt end of the molecule is attracted to water and dissolved in it. The non-polar hydrocarbon end of the soap molecule is repelled by water.The soap molecules "stand up" on the surface as the polar carboxyl salt end is attracted to the polar water. The non-polar hydrocarbon tails are repelled by the water, which makes them appear to stand up.
Soap vs. oils.vs. water:
Water alone is not able to penetrate grease or oil because they are of opposite polarity.When grease or oil (non-polar hydrocarbons) are mixed with a soap- water solution, the soap molecules work as a "bridge" between polar water molecules and non-polar oil molecules. The oil is a pure hydrocarbon so it is non-polar. The non-polar hydrocarbon tail of the soap dissolves into the oil. That leaves the polar carboxylate ion of the soap molecules are sticking out of the oil droplets, the surface of each oil droplet is negatively charged. As a result, the oil droplets repel each other and remain suspended in solution (this is called an emulsion) to be washed away by a stream of water. The outside of the droplet is also coated with a layer of water molecules.
