We take salt for granted as a necessary seasoning for dishes. Meanwhile, this important in cooking substance is a doctor, a magical defender and assistant in the household.
For treatment salt is more often used in a dissolved form. The methods have a number of nuances, which must be known. For example, how to make a 10 percent saline solution, if there are no chemical measuring spoons and beakers at home? How much salt and water should I take? Let's consider simple variants of preparation of medical solutions.
What kind of salt is needed to prepare the medicine?
Before you prepare 10% saline, you need to carefully study the recipe. What substance is mentioned in it? If table salt, the following packages are suitable:
- kitchen salt;
- sodium chloride;
- edible salt;
- rock salt.
In everyday life, the word "salt" is used, although this term refers to many complex substances formed by ions or metal atoms and acid residues. In addition to sodium chloride, for therapeutic purposes, the English salt is used - magnesium sulfate. They extract substances during the development of deposits in the earth's crust.
If you evaporate sea water, you get sea salt, which contains sodium, magnesium, iodine, chloride, sulfate ions and other components. The properties of such a mixture are somewhat different from individual substances. Usually, for treatment of wounds, sore throat, teeth, 1-10% saline solution of sodium chloride is prepared. The chemical formula of the compound, which has amazing properties, is NaCl.
What should be the degree of purity of the components?
How to make a 10 percent saline solution at home, so that the medicine is beneficial, and not harmful to the body? Salt should also be as pure as possible, but purchased in the store "Stone" is often contaminated with impurities. There is a more pure product of fine grinding.
Some recipes recommend the use of snow or rainwater, but this is an unfortunate idea in terms of modern ecology. The purity of the liquid that flows in the systems of domestic and drinking water supply, also causes many complaints. It, like snow and rain, can be contaminated with chlorine, iron, phenol, oil products, nitrates. Let's clarify that distilled or demineralized water is used as a solvent in medicine. Houses for the preparation of the solution can be filtered or boiled water.
If you put plastic molds with water in the freezer, then first pure water will freeze, and impurities will accumulate on the bottom. Without waiting for complete freezing, we must collect ice from the surface and melt. Get very clean and healthy water.
How to measure salt mass and water volume for solution preparation?
Everything you need to collect in advance, before you make a 10-percent saline solution. You will need water, a beaker, a bag of salt, a scales, a glass and a spoon( dining room, dessert or tea).The photo below will help to determine the mass of salt, which is contained in a dessert and a teaspoonful.
Then you need to determine the units for the fluid. It is believed that the mass of 100 ml of fresh fresh water is 100 g( density of fresh water - 1 g / ml).Liquids can be measured with a beaker, if it is not there, then an ordinary glass of those called "faceted" is suitable. Filled to the risks, it contains 200 ml of water( or g).If you pour to the very top, you get 250 ml( 250 g).
What does the expression "10 percent solution" mean?
Concentration of substances is usually expressed in several ways. Most often in medicine and everyday life such a value is used as a weight percentage. It shows how many grams of the substance is contained in 100 g of the solution. For example, if the recipe says that 10% saline is applied, then every 100 g of such a preparation contains 10 g of solute.
Suppose you need to prepare 200 grams of a 10% solution of salt. We carry out simple calculations that do not take much time:
100 g of the solution contains 10 g of substance;in 200 g of solution contains x g of substance.
x = 200 g x 10 g: 100 g = 20 g( salt).
200 g - 20 g = 180 g( water).
180 g x 1 g / ml = 180 ml( water).
How to make 10% saline?
If the house has a scale and a beaker, then the mass of salt and water volume is better measured with their help. To collect a teaspoon "with the top" and pour a glass of water to the risks, too, can be, but such measurements sin inaccuracies.
How to make a 10 percent saline solution to get 100 g of the drug? Weigh 10 grams of solid sodium chloride, pour 90 ml of water into a glass and pour salt into the water, stirring with a spoon until dissolved. Mix the salt with warm water or cold, and then the dishes with the components are heated. For a better purification, the finished solution is passed through a wad of cotton wool( filtered).
Prepare 50 g of a 10% solution from 45 ml of water and 5 g of salt. The hypertonic salt solution is made from 1 liter of water and 100 g of sodium chloride( 4 tablespoons "without top").
Treatment with 10% saline solution
In medicine, a 0.9% solution of salts is prepared on fresh distilled water, which is called "physiological".This fluid is isotonic with respect to the internal environment of the human body( has the same concentration).It is used in various medical procedures, in particular as a blood substitute, to eliminate the effects of dehydration and intoxication.
Hypertensive solution contains more salt, when it comes in contact with an isotonic or hypotonic liquid, it attracts water until the concentrations equalize. This osmotic effect is used in folk recipes to purify wounds from pus. Salt has antiseptic, antimicrobial properties, its hypertensive solutions are used in alternative medicine:
- for diseases of internal organs - in the form of a saline bandage on the focus of pain;
- as lotions, compresses and applications for skin and other infections;
- as saline baths with fatigue and pain in the hands and feet;
- for the purification of purulent wounds.
Treatment with hypertonic 10% saline will take time, it can take several days or weeks. The minimum number of procedures is 4-7.With pain in the throat, 3-5% hypertonic rinse solution is used in the morning and evening. The nasal cavity is washed with an isotonic solution. For its preparation, add 1.27 g of sodium chloride and 2.5 g of baking soda to 237 ml of boiled water.
