Description
Potassium sulfate,K2804, also known as salt of Lemery and arcanite, is a colorless crystalline solid that melts at 1072°C(1960 OF). It is soluble in water,but insoluble in alcohol. Potassium sulfate is used in manufacturing glass, aluminum, fertilizers, and in medicine. Potassium sulfate, sulfate of potash, K2SO4, white solid, soluble. Common constituent of potassium salt minerals.

In case of fire in the surroundings, use appropriate extinguishing media.
Sweep spilled substance into covered containers. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.
Evaporation at 20 °C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
The substance is mildly irritating to the eyes, skin and respiratory tract.
Use local exhaust.
Protective gloves.
Wear safety goggles.
Drug Information
Potassium is used to regulate hypokalemia as a primary condition or secondary to other medical conditions.|Diagnostic of organic and/or functional bowel diseases|Diseases of the intestines
Mostly urine but also skin and feces.
Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential. The balance between potassium and sodium is maintained by ion pumps in the cell membrane. The cell membrane potential created by potassium and sodium ions allows the cell generate an action potential—a "spike" of electrical discharge. The ability of cells to produce electrical discharge is critical for body functions such as neurotransmission, muscle contraction, and heart function. Potassium is also an essential mineral needed to regulate water balance, blood pressure and levels of acidity.
Fresh air, rest.
Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Potassium sulfate Use and Manufacturing
REACTION OF POTASSIUM CHLORIDE WITH LANGBEINITE ORE, SCHOENITE OBTAINED FROM KAINITE ORE, OR SODIUM SULFATE (GLASERITE IS AN ISOLATED INTERMEDIATE); REACTION OF POTASSIUM CHLORIDE WITH SULFURIC ACID OR SULFUR DIOXIDE, WATER AND OXYGEN; RECOVERY FROM SUGAR WASTES|(A) BY TREATMENT OF POTASSIUM CHLORIDE EITHER WITH SULFURIC ACID OR WITH SULFUR DIOXIDE, AIR, & WATER (HARGREAVES PROCESS). (B) BY FRACTIONAL CRYSTALLIZATION OF NATURAL SULFATE ORE; (C) FROM SALT LAKE BRINES.|THE POTASSIUM SALT OF SULFURIC ACID. ...FIRST POTASH SALT PRODUCED COMMERCIALLY IN US FROM ANYTHING OTHER THAN WOOD ASHES. IT WAS PRODUCED FROM ALUNITE. SULFATE HAS ALSO BEEN MADE FROM CEMENT MILL DUST, LANGBEINITE, & FROM MURIATE BY TREATMENT WITH SODIUM OR MAGNESIUM SULFATE OR WITH SULFURIC ACID.
Used as a chemical fertilizer to enable economic plants to achieve sustained high quality and high yield, used in tea, vegetables, fruits and other crops; used as an analytical reagent (such as nitrogen determination), and also used in the synthesis of potassium salts and dietary substitutes for pharmaceutical industry use Salt. Used as a chemical fertilizer in agriculture. It is the raw material for making potash. The dye industry is used to make intermediates. Used as a fining agent in the glass industry. Used as auxiliary agent in perfume industry. Used in medicine as a laxative. Used as a general additive in the food industry. It is also used for serum protein biochemical test. Uses: Used as potash fertilizer, and also used in glass, dye, perfume, medicine and other industries. Serum protein biochemical test, determination of serum potassium and other potassium salts, Kjeldahl catalyst for nitrogen determination, preparation of other potassium salts. Special for glucosamine sulfate, medicines and health products, chemical reagents. Used as medicine, potash fertilizer, and used to make alum, glass and potassium carbonate, etc.
