Documented Uses

• A white crystal or crystalline powder used as an electrolyte replenisher, in the treatment of hypokalemia, in buffer solutions, and in fertilizers and explosives. [ChemIDplus]
• In photography. In buffer solutions, electrode cells.
• Potassium chloride ... or muriate of potash (MOP) as it is known in the fertilizer industry (at about 97% purity), is the world's most commonly used potash. Chemical-grade potassium chloride (99.9%) is the basis for manufactured production of most potassium salts ... It is used in aluminum recycling, in the production of potassium hydroxide, in metal electroplating, oil-well drilling mud, snow and ice melting, steel heat-treating and water softening.
• Fertilizer, source of potassium salts, pharmaceutical preparations, photography, spectroscopy; plant nutrient, salt substitute, lab reagent, buffer solutions, food additive.
