Preparation of potassium nitrate

(there are potassium nitrate formula uses and definition)

Potassium nitrate (KNO3) is a chemical consisting of potassium, nitrogen, and oxygen and is a flammable auxiliary material because it contains three oxygen atoms and enters into the synthesis of gunpowder and is available in the market as a fertilizer rich in nitrogen. This material is present in nature and can be extracted by dissolving a soil rich in this salt (potassium nitrate) in water and then cooling the solution to precipitate crystals of this substance, and can be prepared industrially by the reaction of potassium hydroxide with nitric acid. How to prepare

We prepare potassium hydrate or what they call soap makers Qatrona, a key material for the industry Soap with olive oil, a caustic skin, please do not touch it Put this material in a glass jar with a little water We pour a barbij out of the pot and prove the end of the syringes We pour the nitric acid inside the syringes a little bit until

The acid arrives in potassium water so that the white steam does not smell the reaction because it destroys the lung Upwind the wind and the length of the barbij more than two meters to be in the proportion of materials

One hydrate with 1.2 acids according to the equation and atomic weight Prefer to place the pot inside the ice container so that the heat does not rise

After completion, wait for the solution to cool down and observe the formation of potassium nitrate crystals 6- It can be boiled to get rid of Dampen or dry in the sun for two days

Note that when boiling, water evaporates before the substance boils because it boils more than boiling water Potassium nitrate is easy to dissolve in water.

Potassium: Potassium works with sodium, in monitoring the balance of fluid in the body, transfer of nerve orders, muscle contraction and maintaining the integrity of the heartbeat.

Most types of food contain sufficient amounts of potassium, so it is rare that potassium supplementation is needed. However, mild deficiency may occur in people who drink coffee or alcoholic beverages in excessive amounts, or those who eat more salty foods, as well as diabetics.

Symptoms of deficiency :

Symptoms of early potassium deficiency include muscle weakness, fatigue, dizziness, and confusion. It can damage the nerves and muscles, which can lead to a disturbance in the heart rate, paralysis of skeletal muscles and intestines, which may lead to constipation.

Symptoms and risks of overdose :

The level of potassium in the body is controlled by the kidneys, so that any excess amount is excreted through the urine. Doses greater than 18 grams may lead to heart rhythm disturbance and paralysis of some muscles. In people with impaired kidney function, excess potassium may accumulate in the body, increasing the risk of potassium poisoning.

Pharmaceutical preparations :

Potassium chloride, potassium gluconate, and potassium compound – homocysteine ​​can be obtained without a prescription. Potassium chloride and potassium gluconate are widely used in sodium-free salt (salt substitute). Additions of potassium citrate and potassium castrate are given only by prescription.

Sources :

The best sources of potassium are green leafy vegetables, oranges, grapefruit, potatoes and bananas, as well as red meat, legumes, and milk. Many food processing methods may reduce the amount of potassium in food.

Dosage required :

The dosage is determined individually, depending on the type of preparation, the cause of potassium deficiency and its severity. In general, a dose of between 2 and 6 grams of potassium chloride is given to avoid deficiencies, for example – for people treated with several types of medications, which cause a deficiency of potassium. To treat the deficiency, a dose equivalent to 3 – 7.2 potassium chloride is given.

Types of foods containing vitamin/mineral:

  • Bread and cereals
  • Pulses
  • Green
  • vegetables
  • fruits

Use of potassium nitrate

Potassium nitrate is a flammable substance, it is used in a number of industries such as gunpowder. It is considered the first and main component for the manufacture of firecrackers, fireworks, explosives, and fertilizers. It is also used in the manufacture of lighting candles and meat preservatives.

Preparation of potassium nitrate at home

Components and tools

  • A quantity of soil, taken from fallow land, unfit for agriculture, from a dirt house, old building foundations, from soil containing decaying vegetables, or goat manure.
  • Boiling water, taking into account that the amount of boiling water is equal to the number of materials used.
  • Medical Spiro.
  • Vase with a narrow nozzle.
  • Normal sieve. Saucepan.
  • Charcoal filter, which means a quantity of coal, placed in a cloth, controlled according to the shape of the sieve, which will be used in the process of filtering water and materials used, taking into account that the thickness of this filter does not exceed 1 cm.
