  • Chemical Properties
    • white crystals or powder

  • General Description
    • White colorless cubic crystals. Strong saline taste.

  • Air & Water Reactions
    • Hygroscopic. Water soluble.

  • Reactivity Profile

    Potassium chloride is not in general strongly reactive. Violent reaction with BrF3 and with a mixture of sulfuric acid potassium permanganate mixture . Reacts with concentrated sulfuric acid to generate fumes of hydrogen chloride.

  • Usage
    • May be used for the preparation of phosphate buffered saline, and for the extraction and solubilization of proteins.

  • Health Hazard

    SYMPTOMS: Large doses of Potassium chloride usually induce vomiting, so acute intoxication by mouth is rare. If no pre-existing kidney damage, it is rapidly excreted. Poisoning disturbs the rhythm of heart. Large doses by mouth can cause gastrointestinal irritation, purging, weakness, and circulatory disturbances.

  • Fire Hazard

    Flammability data is not available, but Potassium chloride is probably nonflammable.
