Why Water and Sodium Titrate is only use for the Calibration of Karl Fischer Titrator ?<\/h2>\r\n\r\n\r\n\r\n

\r\n
• Sodium tartrate dihydrate is the volumetric standard for Karl Fischer titration. Under normal conditions, it is stable and non-hygroscopic.<\/li>\r\n
• Sodium tartrate dihydrate has a stoichiometric water content of 15.66% and is mainly used for titer determination in volumetric.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n

  Karl Fisher Titration<\/h2>\r\n\r\n\r\n\r\n

  \r\n
  • Karl Fisher Titration is a method for the determination of moisture content. The technique was established by a chemist named Karl Fischer. It is based on a mixture which reacts with water and converts the water into a non-conductive chemical. Karl Fisher provides for the specific detection of water. There are two methods used to perform the Karl Fischer titration test.\r\n

      \r\n
      • In this method, the moisture determination is based on the amount, or volume, of reagent used to convert the water.<\/li>\r\n
      • Samples are dissolved in a solvent before the titration begins.<\/li>\r\n
      • A reagent is added until the water is removed.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n

        Coulometric Karl Fischer<\/h2>\r\n\r\n\r\n\r\n

        \r\n
        • In this method, the reagent and solvent are combined in the titration cell.<\/li>\r\n
        • When a sample is introduced into the titration cell and dissolved, reagent is released by the induction of an electrical current.<\/li>\r\n
        • The amount of current required to convert the water is the determinant of the amount of moisture.<\/li>\r\n
        • A Coulometric Karl Fischer instrument is often referred to as a coulometer.<\/li>\r\n<\/ul>\r\n","protected":false},"excerpt":{"rendered":"
