  • Potassium Chloride

    CAS NO: 7447-40-7

    MOLECULAR FORMULA: KCl

    MOLECULAR WEIGHT: 74.55

      Alternate Names:  Potassium Chloride is also known as KCl.
      Application:  Potassium Chloride is a common laboratory reagent and   calibration standard for measuring electrical conducivity.
      Purity:  >99%
      Description:  Potassium Chloride is commonly used as a laboratory reagent   as  a standard. Potassium Chloride may be used as a calibration   standard ionic solution for measuring electrical conductivity   because Potassium Chloride solutions, when prepared   carefully,  produce repeatable measurable properties.   Potassium  Chloride is also a good source of ionic chloride,   which should precipitate insoluble chloride salts upon addition   to a solution of an appropriate metal ion. Oral Potassium   Chloride is commonly used to replenish vital potassium in the   body, and has also been shown to lower blood pressure.   Potassium Chloride is commonly used in fertilizer.
