Products Name: Agricultural fertilizers Potassium Nitrate
Molecular formula: KNO₃

Molecular weight: 101.10

CAS: 7757-79-1

Chemical properties

Potassium nitrate has a molar mass of 101.10 grams per mole. It has a boiling point of 400 °C (752 °F), a melting point of 334 °C (633 °F), and a density of 2.11 grams per cubic centimetre at 25 °C (70 °F). It is soluble in water at 38.3 grams per 100 millilitres at 25 °C but is only slightly soluble in most alcohols. It is insoluble in ethanol.

Description:

Agricultural fertilizers Potassium Nitrate is a chemical compound fertilizer. It is salty and a bitter taste with chemical formula KNO3. It is a source of nitrogen.

Character: Agricultural fertilizers Potassium Nitrate is white color or colorless transparent particles or crystalline powder. It is highly soluble in water, insoluble in absolute ethanol and ether. When it is dissolved in water, it can absorb heat so the solution temperature can reduce.

What is potassium nitrate mainly used for?

Uses of potassium nitrate include the manufacture of fertilizers, pesticides, glass, fireworks, explosives, and rocket fuels. It is also used as a food preservative, and when added to meat it causes a reaction between the myoglobin and hemoglobin in the blood, making the meat appear red in colour.

Is potassium nitrate toxic to humans?

Breathing Potassium Nitrate can irritate the nose and throat causing sneezing and coughing. High levels can interfere with the ability of the blood to carry Oxygen causing headache, fatigue, dizziness, and a blue color to the skin and lips (methemoglobinemia).
