Disodium tartrate contains fixed amount of water of crystallisation according to its molecular formula and is available in pure form. Hence, it is considered as a primary standard for standardisation of Karl Fischer reagent. Alternatively, we can try distilled water also for standardisation of KF reagent. Theoretically, 1 mL of KF reagent is equivalent to 5 mg of H2O (water).
