What is limit for water content (acceptance criteria ) of disodium tartarate , during calibration of KF
Ideally, one ml of Karl Fisher reagent corresponds to 5 mg of water as H2O. Accordingly, you can check the accuracy of your KF instrument. It should be within 95 to 105 percent as there is no specific guideline. KF factor nearer to 5 mg of water is acceptable. You can find theoretical quantity of water of crystallisation in disodium tartrate from its molecular formula weight.
Acceptance criteria is 4 to 6…
