Brine or salt of potassium nitrate is a chemical compound with the formula K(NO3) 2 , potassium nitrate contains 45% K 2 O and 10% nitrogen. Due to its explosive properties, 80% of potassium nitrate and 20% of potassium chloride are usually used in the preparation of chemical fertilizers. This substance exists naturally in places like the walls of caves in a white round form. Potassium nitrate is
Brine or salt of potassium nitrate is a chemical compound with the formula K(NO3) 2 , potassium nitrate contains 45% K 2 O and 10% nitrogen. Due to its explosive properties, 80% of potassium nitrate and 20% of potassium chloride are usually used in the preparation of chemical fertilizers. This substance exists naturally in places like the walls of caves in a white round form. Potassium nitrate is a fairly strong oxidizer. Potassium nitrate salt is a natural mineral that contains three main chemical elements. These elements include potassium (a soft and bright metal), nitrogen (a colorless and odorless gas) and oxygen.
Potassium nitrate has moderate solubility in water, but its solubility increases with temperature, this increase produces an ascending graph. Having the solubility values in a certain amount of water at different temperatures, one can find other required unknown values. Aqueous solution of potassium nitrate is almost neutral. Potassium nitrate is not very absorbent. Potassium nitrate is insoluble and non-toxic in alcohol; Potassium nitrate reacts explosively with reducing agents, but has no explosive properties by itself. Potassium nitrate is produced from the combination of ammonium nitrate and potassium hydroxide. An alternative method to produce potassium nitrate without the ammonia byproduct is the combination of ammonium nitrate and potassium chloride, which is easily obtained as a sodium-free salt substitute.
Important values of the solubility of this substance in 100 grams of water are as follows:
In general, the dissolution relationship of this ionic salt in water is as follows:
The solubility of this substance per degree Celsius is equal to 1.6 grams per 100 ml of water.

Potassium nitrate is mainly used as a source of nitrate. In the past, nitric acid was produced by combining sulfuric acid with nitrates such as potassium nitrate, but now nitrates are produced from nitric acid produced through the Ostwald process. The most famous use of potassium nitrate as an oxidizer in black powder today is in rocket engines. Potassium nitrate is also used in smoke bombs. Other uses and applications of potassium nitrate include the following:
